Anybody here with 1st hand experience on using PSVANE tubes?
Like most newbies on tubes, Ive been reading on some stuff in the net and came across these:
PSVANE 12AX7
(http://i243.photobucket.com/albums/ff199/x_pit/pavane12ax_zps5ce6f988.jpg)
PSVANE 12AU7
(http://i243.photobucket.com/albums/ff199/x_pit/12au7_zps55bcab97.jpg)
PSVANE EL34/6CA7
(http://i243.photobucket.com/albums/ff199/x_pit/el34_zps8efb85d1.jpg)
I know it's common knowledge that NOS tubes are better than current production ones, but with NOS tube prices going nowhere but up, and supplies going nowhere but down, I thought maybe there's hope in current production tubes, hence the question. :)
Hope to hear from you guys, particulary those who have had extensive experience with tubes.
Cheers :)

Current production tubes haven't caught up yet with NOS tubes in terms of quality, but certainly a day will come when they can be even better.
For availability and pricing, PSVANE tubes and other current production tube are worth trying out on your tube amp.
A tube amplifier without tubes is just a mere power supply. Tube amplifiers are made to sing music be it pleasant to the ears or not.
Please post your sonic experience with the PSVANE tubes.

I think these are available in Audio Amplified in Libis... :)

i have NOS tubes and some new production tubes that i bought.
it would be not be quite accurate to say NOS tubes are better than current production . when one say one is better than the others-- they should say why it is so
NOS are expensive because of rarity and collectibility.(law of supply and demand) Ownership of such items makes one proud, since to them the sound produced by such NOS also are rare.(that's what we call "pride of ownership" and "bragging rights"), though yes, there are NOS tubes that sounds great...but there are also new production tubes that sounds great too... BUT , the thing is-- there are lots of NOS tubes around that sounds mediocre when installed in one's audio system... same thing with new ones-
so, the general statement or sweeping statement that NOS are better than current production tubes doesn't hold true in these cases.
depending on who's giving the review, Detailed sound to some becomes Talas sa tenga while Warm sound means ngongo to others. We should also take note of the music preference of the reviewer.
i still doubt the idea that NOS tube can not be cloned. We live in the modern world of computers and with high tech facility around and given the advanced state of science and technology we have today (and btw, it's almost 2013-so happy new year!), it would be easy for any factory with modern facility, to clone any tubes (made in the copong-copng era like the 1950s and 60's ), if the objective is to copy the SQ character , using reverse-engineering.
Also,We should take note of who is giving a review. The best source are buyer's reviews .
They don't have to push stocks for sale.
(Sellers may be bias with what stocks they have to sell , be it new production or nos.)
a lot of consumer review say psvane tube are that good!
i heard psvanne peanut tubes on my friend's integrated amp , and sure, they sound great.
but it has other tubes as well. i haven't heard others for comparo... might be the combination.
the thing is--i already ordered them anyway,and waiting for the 12ax/au's to arrive

Point well taken :)
Hope to hear from you sir when those peanut PSVANE tubes arrive... I'm quite interested in those as well, at least the small ones first... From what I saw in the net, I think this PSVANE tubes dont come cheap.
Thanks sir and Happy New Year!!
Cheers!! :)

that is why i'd rather use TV tubes than use these china tubes.... ;D
before i get flamed, i would say a designer worth his salt will design tube amps based on what is available....if you have a pasvane tube, so be it, optimise your circuit based on that tube...
if my amp sounds different each time i change tubes, i get depressed, that means that i failed.... 8)
btw, my Shuguang EL34 pp amp rocks....my opinion of chinese tubes changed because of that.... ;D i am going to try the 6550 and KT88 tubes on that amp...

you are on the money there attorney, always a voice of reason...........an amp is not made up of just the 12ax7 or 12au7 alone, you have the opt there as well, the OPT alone is the single deal maker or breaker.....i have yet to see audiophiles rolling opt's.... ;D
Finally, why spend money on an amp that you will need to spend more money to get the sound right? to you liking, why not just buy those tubes and build the amp using those parts? there are tube rollers, capacitor/resistor changers why no OPT changers as well? ;)

No need to get flamed on this one sir. I, like most of the guys here, read on and research on this common hobby that we all share. Subjective as it is, in one way or another - there is still some science involved in it, or a dark art perhaps... Whatever it's called. Insights, opinions and experiences from you guys - the experts, are very much appreciated. It's like an educated opinion :)
Some would roll tubes, some caps, some would even do it with amps and speakers...For some, it gets very expensive, and for some - not much... It's all part of the fun anyway... At the end of the day, were all happy and enjoying music (and movies), in whatever way it sounds.
Cheers to all and Happy New Year!! :)
More audio stuff for all of us this 2013 ;)

we know for a fact tha psvane tubes are chinese-made!
and there's a lot of good reviews regarding these tubes....
btw, my Shuguang EL34 pp amp rocks....my opinion of chinese tubes changed because of that.... ;D i am going to try the 6550 and KT88 tubes on that amp..
if this is the same EL 34 amp i heard at the last hifi show @dusit, aba.. it's a great sounding amp...
maganda tumunog ito, tony..me narinig pa nga akong nagsabi ..asan yun subwoofer?!!! :)
i have shuguang EL 34 too...Good sounding tube yet reasonably priced .(provides a different flavour
with the mullards i have)
btw, since we are talking about chinese tubes...let me quote something i found on the net years ago.
we know many audiophiles consider the WE300B tube as the holy grail of tubes!
one good product of shuguang is their 300Bs whch has been rebranded/ relabelled several times
by different companies
a case in pt, shuguang 300B is the same tube relabelled as valve art as per tubestore.com
http://thetubestore.com/300btypes.html
also from http://www.jacmusic.com
Valve Art 300 B
A perfect copy of the WE 300B. I noted the filaments are exceptionally powerful even at lowered temperature. I can almost say for sure, they still use the ancient recipe for Thorium-doted filament Coating. (Older form of Barium coating). For the factory workers, this is a dangerous material, and this is not allowed to be used in Europe and the USA since many years now. Whatever their secret, the filaments work great. Don't worry... thorium is used in every NOS tube, and there is just a micro trace in a finished tube.
High Resolution image <Images/300B-Valve-Art.JPG>
labor laws in the US are strict when it comes to the use of dangerous substance like thorium unlike in China so what this means is
that if thorium content is used in every 1950 western electric 300B tubes then Chinese firm have no problem using the same substance in cloning that tube.
i suspect ,the new production WE300B (US- made) might have a different recipe than the old 1950WE 300B. .. and if chinese shuguangs have the same recipe, your guess is good as mine.
you are on the money there attorney, always a voice of reason...........an amp is not made up of just the 12ax7 or 12au7 alone, you have the opt there as well, the OPT alone is the single deal maker or breaker.....i have yet to see audiophiles rolling opt's..
i assent. the quality of OPT is indeed a single deal maker or breaker...
that's why a friend of mine bought some premium priced opt@hk.
eh pano kung OTL :) :) :),, amp rolling mode na
happy new year bro! :D
-
i have yet to see audiophiles rolling opt's.... ;D
I knew a few who rolled their opt's with James and Tamura opts. In my opinion, huge difference and excellent investment.
-
if this is the same EL 34 amp i heard at the last hifi show @dusit, aba.. it's a great sounding amp...
maganda tumunog ito, tony..me narinig pa nga akong nagsabi ..asan yun subwoofer?!!!
with a Russian 6j9(ef180/6688 equivalent) and a Japanese(hitachi) 6CG7 how can one go wrong? i guess the Russian and Japanese can push the Chinese around..... ;D
-

let us not forget that there are Hashimoto and Lunhdall traffos as well.....
yes, i agree that those OPT's are better than the OPT's originally supplied in the Chinese amps.....aba, Edrel and Mang Rey can make better OPT's given that M6 type cores are still available in our local surplus core market....Edrel's Z11 cores are tops, i use them in some of my OPT builds, a bit pricey though...
last year i had a chance to repair a KT88 branded PP power amp, nalubog sa baha, so opening the cased OPT revealed a core with 1 inch center leg, this the type of OPT i used in my 6LU8 pp amp......my EL34 pp amp used 1 3/4 inch cores, the Dynaco ST70 btw used a 1 1/8 inch core in the A470 OPT, this is a well regarded OPT mind you....

hehehe....happy new year attorney......i might just make your wish come true.....just awaiting some parts from china....
amp rolling....yes i agree, i ussually recomend T-amps nowadays as a second amp, parang atsara, pag naumay sa tubes T-amp naman....
i built one for a guy that owned a 2A3 single ended amp and he said the T-amp sounded like his SET....

Well I was going there actually, support Edrel's trannies, he knows his stuff real well.
Those encapsulated trannies I repaired moons ago are total crap! Sa iyo 1" pa nakita mo, eto 7/8" lang and it's used in a PP EL34!!! Kakainis ano? Wag na natin post ang brand. ;)
I know about the A470, I have a pair of original ones but if I were to build another tube amp it will surely be using Edrel's.
Teka Happy New Year pala sa iyo tony at sa lahat ng tubero! ;D
Kampay!

i do have a sonic t-amp. -recasing and power supply made by master jojod .
kasing tunog ba ?? ng 300B amp ko haha , tipid pa sa kuryente.

there are lots of russian tubes that i like . kahit na yun 6N1p nila , gusto ko sa tube buffer.
Russian sovtek 12ax7LPS- -favorite peanut tubes ko sa JD-9. The new production tungsol 6SN7 is another favourite of mine.... pang sub ko sa Sylvania, CBS 5692 at hitachi

meron metal base na russian 6SN7 na mura lang dati, skyrocket yun presyo niya ngayon sa $120-$169 a piece ata?

I tried using a psvane 12au7 with my amp but it was 12ax7 originally it was good but a little lower in gain.. Then swithched to jj 12ax7 an its fatter sounding more solid so i preferred the JJ gold pins. I know i shouldnt compare the 2 coz its different gain but sound wise in my amp JJ wins.
-
JJ is Russian new production tubes, locally available here...http://www.epektos.com/catalog/90270c5d-17be-428d-8204-30703444af81.aspx
Pasvane is China made....a look at the gold plating on the pins and the fancy casing tells you it's not going to come cheap......there is a market for these expensive tubes, there are those who scorn cheap tubes and cheap amps as low quality...
Shuguang tubes are available here......http://www.goodcomponent.com/ they carry both the cheaper and more expensive versions.....so there is something for everybody....;D

yes those Russian metal based 6sn7 really cost an arm and a leg, so that is what happens when an item is hyped and an apparent demand for the tube is created, cost skyrocket.....
-
hype = bad for us :'(
-
IME, I've had more infantile mortality issues with Chinese tubes than Russian tubes. I'm talking stock tubes that came with the units (Chinese) and new productions Russian tubes. I do have specimens of both that up to now are still working, maybe it has something to do with their quality assurance programs.
hype = bad for us :'(
good thing this bowl of 6sn7 tubes has insured my personal tube gears to last my lifetime...

I will probably try first the cheaper tubes and see how my amp responds, and as per Sir TonyT's advice, will probably try the JJ Tesla tubes first (locally available and reasonably priced).
Once I get a better understanding on how the amp sounds on rolling, the inherent character which remains constant and the tones that change upon rolling, then maybe I can start trying out these "premium" tubes.
I do hope those who've tried these tubes would still give in their inputs and observations - those would still be highly appreciated. If the said tubes are "bang for buck" or just a complete waste of time and money.
Hope to hear more from you guys.
Thanks! :)
-
" bang for the buck?" those will be TV tubes..... ;D
the 6LU8 tubes i used in my 12 watter pp amp costs just $1 dollar each and yet give very decent performance....... ;)
why not just try those psvanes and then tell us...
-
JJ are very good specially for the price very cheep but very good.. Try to borrow tubes muna and see what will fit in your gear and taste. I also compared a new sovtek and a nos philips 12ax7 obviously the philips won but not that much. Even my friends was shocked the difference wasnt that big.
-
Russian tubes are better than Chinese tubes for the simple reason that the Russians have been doing it for the longest time and has more experience, materials available to them......i have not met a Russian tube i did not like....
Russian tubes are much cheaper too...a pair of GU-50 pentodes can make 80 watts in pushpull...yest cost lower than other types...
-
Will probably try the cheap russians first, JJs then perhaps compare it with some chinese, psvane and shuguang... If by any chance other brands pop up that are quite cheap, then maybe those can be considered as well. :)
When i get those tubes in hand, I will invite you guys over to have a listen. Para madaming opinions sa A/B/C. :)
And a good way of meeting people din yun. :D
-
Good call give us updates on the result ng tube rolling mo.. :) good luck bro. If you can borrow a set of genalex gold lions to compare, i heard its one of the best reissue tubes today.

Not all NOS tubes are created equal. And same thing also with modern production tubes.
Kaya nga may mga gold standard na NOS tubes that are being used as reference. Yung mga modern production ay ginagamit din ang NOS as their gold standard also.
Most tube amps manufacturer in US are ordering tubes that are made according to their specifications. Yung mga nabibili sa mga resellers ay minsan mga rejects or low standards.
I just ordered TJ mesh globe 300B mesh from a reseller in HK. At 60 ma plate current , nagbabaga ang plate at manipis ang tunog. Yung mga early production ng TJ 300B ay maganda ang tunog na gamit ng friend ko sa SET amp nya hanggang ngayun.
-
) good luck bro. If you can borrow a set of genalex gold lions to compare, i heard its one of the best reissue tubes today.
gawa rin sa russia yan genalex gold lions . just to show you there are lot's of quality new production tubes
around as long they are bought from reputable source that even provides matched tubes with ratings when preferred.
btw,last time i visited andrew's amx store in paranaque. i bought some JJ's .. it's a good buy indeed!
bro meateater, there might be some jjs and even some sovteks available there.
mind you, not all sovtek 12ax7 are the same. what i recommend is the one with lps-- 12AX7-LPS...
]Most tube amps manufacturer in US are ordering tubes that are made according to their specifications. Yung mga nabibili sa mga resellers ay minsan mga rejects or low standards.
this is very true. i suspect that when an item is priced lower than the prevailing average market rate, the item might be seconds or napag-pilian na .
-
no two tubes are exactly alike, even tubes of the same part number and manufacturer, the law of statistics play a major role....
ditto these double triodes, each half is seldom identical, finding ones that measures exactly alike is a stab in the dark....
that is why tube designs take this into consideration....
this explains why tube rolling produces perceived differences in sounds.....
-
this is very true. i suspect that when an item is priced lower than the prevailing average market rate, the item might be seconds or napag-pilian na .
there are tube vendors in the states that indicate if the tube they are selling are pulls or NOS....the pulls are lower than NOS, sometimes by as much as 50%...
but as with all commerce, there are risks....
-
Thanks for all the tips mga peeps :)
-
JJ 12ax7 are winners indeed.. :) a lot cheaper than psvane or gold lions. I whole heartedly recommend this!
Before i bought the jj el84 im being sold a sealed tele for a very good price temping but since its sealed i dont have any guarantees na it would be a good tube so just to be sure i bought the jj's and i made a good decision. Similar din on other nos tubes unless the seller can be trusted or the tubes are tested.. Of couse my factor din na it might not suit my system or my likings sayang pera unless collector ka and you have the money to burn..

ok din ba yung 12au7 nila? hehehe
Say the amp is to run on JJ "smalls", 2 x 12ax7 + 2 x 12au7? oks kaya yun? Hopefully so. :) If not, tubes would roll and end up sa fs section. hehehe
It's one of the things na nagustuhan ko sa tubes, you can cater the sound to your liking by simply replacing the tubes instead of changing amps or speakers. :D
Thanks sir! nice tips! :)
Oh btw, baka me alam kau mga sir san makaka kuha nun 12au7, I dont think epektos has it in their site.
Cheers :)

^sir try to inquire in Kinetic Audio(AMX).
I saw some JJ tubes before when I picked up my preamp last Dec :)

will give Mr Sevilla a call soon if me mga JJ's sila dun. I would love to change the el34's din soon, pero sa summer na since the amp is still covered under warranty, and biasing the amp might void the warranty (bias pots are underneath the chassis :( ) - Also, I think its best for me to leave the biasing thing to qualified guys because i have no idea on how to do that, and with extremely high (fatal) volatages running around the amp, I dont think its for me to tinker about :D

salamat brader. pm mo na lng sakali how much. i've read in some sites yun kasi ang better replacements sa yaqin ni bro karl. won't use it naman, will just keep them and burn 1st ung unang mga tubes.
-
oh btw... the PSVANE tubes are quite expensive, but garnered rave reviews abroad.
4500 pesos per matched pairs of 12ax7...
I think i"ll try the JJ's first, those are way cheaper, then maybe someday these premiums from china, or nos stuff perhaps :)
Thanks mga peeps. :)

nyak, mahal nga....hehehe....try to move slowly going up sa tubes. sayang kasi kung bibili ka ng mahal tapos hindi mo naman gusto ung kalalabasan. you might end up selling them.
i guess we are on the same route, tube rolling. but for me, it will take some time before i change them. magtatabi lang sakali magsawa sa tunog.

Once I get a better understanding on how my amp sounds on rolling, the inherent character which remains constant and the tones that change upon rolling, then maybe I can move my way up on the "premiums".
Still a tube newbie here and learning the ropes ika nga. :D hehehe

It's not much sir, but it sounds very good to me as it is.
Curiosity is just knocking on my lizard brain's door about the possible improvement (and possible degradation of sq din) upon rolling.

Almost a year na, and no complaints whatsoever :)
It's one of those things na, will probably stay with me untill ma sira na sia.... This amp will probably never hit the market place section :D hehehe :D

kelangan mo na nga magpalit or mag tube roll..hehe...1yr na eh...its good to have that kind of item na pang matagalan na for keeps....as for me, mabutingting kasi. makati ang mga kamay. ilang watts and ohms speaker mo bro?

Ang alam ko, 120 (max) and 8 ohms prior to customization. The speakers are now with ring radiator tweeters, so I guess nominal impedence is probably around 6 ohms... not sure on this though, I could be wrong. :)
Anthony knows it more than I do, probably by about a billion times more. hehehehe
It's connected to the 8 ohm tap now, and sounds very good to me. I havent tried the 4 ohm tap though...

Havent heard the jj 12au7.. But i bet is good as the 12ax7. Also If you want to change the EL34 and want it cheap try also using JJ's but if you want to go higher gold lions reissue or even higher nos mullards.. :)

bro, how about mullard cv4024 and tungsol 12at7 combi?
-
Ok mullards ung tungsol havent tried it yet. Sa 12at7 i'll go for rca one of the best mura pa i got west germany telefunkens made the sound thinner good sa details ok sya for dark sounding systems which ung mga new tube amps are not..
-
easy on the sockets, you will notice that in time your sockets gets loose and that will give another dimension to the sound..... ;D

Current considerations for rolling
1. Sovtek LPS
2. JJ tubes
3. Tung Sol (re issue)
xx. Genalex (pricey per pair :( )
xx. Psvane (pricey per pair :( )
hehehehe

sensya na po sir tony, it was supposed to be 6n1p ev po yung tinutukoy ko aside sa jj.
the 6n1p can be used to to replace 12au7 but you have to rewire the filament as pins 4 and 5 uses 6.3 compared to 12 volts of the 12au7's......
also beware when substituting 6n1p in place of the 6922/6dj8, the 6n1p uses more filament current, make sure your system can tolerate this, me naencounter na ako na ganyan, nasunog yung power transformer....

12au7 x 3 of Genalex Gold lion = impression = more lush at end well rounded very musical ;D
(http://i460.photobucket.com/albums/qq327/MangBoy31/IMG_0546_zpsa327dd2d.jpg)
12AT7 Mullard black sable was use in mono pre amp = impression = very good imaging and good sound stage and the noise floor was so amazing soo black ;D
When combine with Genalex the sound was very musical with lots of tube characteristics as compare to previous tubes lots of improvement overall. Now I experience, in tube amp you can change the sound characteristic by "tube rolling" very satisfied with the result gold lion gives more lushness and detail but without fatiguing the ear, mullard gives good sound stage and better imaging. :) :) :) cant wait to fully break-in the tubes.... Thanks!
Bro meat_eater hindi pa ako nakakapunta ng manila but I will PM you pag punta ko! ;)

Just rolled in NOS GE 12AU7 and Sovtek 12AX7WXT....
Initial impression of the combination is that tone is much rounder, a LOT less harsh in the top end than the chinese stock tubes, vocals are more lush - much more air so to speak. The bass is good and tight, and the mids are more present than ever.
Just like the stock chinese, the 2 pairs gave no hiss or hum. Dead quiet.
The Russians though, are more prone to microphonics than both the chinese and the NOS GE. A little tap proves this.. hehehe
I wasn't able to try the tubes one at a time, because the combination was done out of excitement, so I wont be able to give insights on the sound of the individual tubes.
Overall - These tubes really complimented each other, and safe to say - This combination will BLOW away the stock chinese 12AU7 and 12AX7 in every way.
I will give my more detailed insights on the said tubes once the tubes have settled in, I will give it 50-200 hrs to burn in, just in case there will be noticeable sound difference.
Special thanks to Voltraizer... Nice chat sir :)

Sorry sir, I cant give you an exact answer. There are far more capable guys here than I am with extensive experience on tube rolling.
For what I know, there is really no way of telling how one tube, or a set of tubes will sound in your system, you will just have to try. :)
One that sounds good in one system may not hold true for your system, again, system matching, tube pairing, and amp wiring and design come into play.
If youre on a budget, try the JJ tubes. Shugaung tubes, although chinese (Yeah, it has a negative stigma :)) when paired with the right tubes, sound pretty good as well.
Again, experiment nalang sir, it's part of the fun ;)
Tube rolling, be it for good or bad, is part of the "audio journey".
Cheers :)

10 hrs in...
And all I can say is that the the stocks tubes dont really compare as far as SQ is concerned. Way WAAAAY behind yung old tubes....
Tones are delivered with a sense of weight and depth, A hint of sibilance could still be observed though when playing treble happy recordings, particularly female vocals (Claire Teal - Chasing Cars *Voices of Love; Woong San - What the world needs now *Best Audiophile Voices 7), but those are almost completely eliminated, hopefully by the 50th hr, the sibilance issues would be insignificant.
Generally, the combination really proves to be lass harsh. A lot less fatiguing to the ears. Like now, I'm on my 3rd hour of listening and It's like I'm being drawn to listen more, however - I would have to limit myself to 3 hrs max/day because tube amps aren't the most "Meralco friendly" devices out there. Hehehe
In a nutshell - I've never heard vocals sound so good in my system before :) - A very happy camper here.
Also, Ive noticed that upon power up - These tubes glow slowly, unlike the Chinese tubes it replaced, where one tube would have a certain "flashing", where it glows bright for half a second, then mellows down like the rest. Now, I only get a simultaneous gradual glowing from all 8 tubes (Pream tubes + 4 el34s).
Hopefully, the sound improves pa in the next 100 or so hrs. If wala na, I'm still happy with this one. :D
Cheers. :)

you must distinguish if the sibilance is caused by the recordings itself or an addition caused by the gears introduced in the chain..
that's why some preamps are designed with tone controls since not all recordings are made equal with respect to SQ..
if the sibilance is embedded in your source music, then there's not much you can do about it...>
unless, you have tone controls to play with, to make bad recordings more listenable.
sometimes, you only need to turn off that audiophile-anayltical mode the way you listen to car audio,
and perhaps , you'll just hear more music, less distraction, then relax and enjoy more!
cheers :D :)

When I'm really tired and just sound trippin, I sit back and relax.... Enjoy it as is. Hehehehe... :)
I have to agree with you on that, there are times (most of the time actually), sitting back and enjoying the music is what it's all about in the end. :)

2!/(100-2)!....and lots of probabilities........I will just listen to my favorite Amp and use as a benchmark then compare it to other similar tube amps then decide!!!! You are right this hobby is something to do with "Self Actualization" as long as you have money to buy it's unending business....
