Audio Amplified, Kinetic/Phasetron, Architectural Audio carry tubes.
Or you can post at the marketplace that you are looking for tubes.
What kind of tubes would you need?
I buy tubes from people who sell at the marketplace, from tubedepot.com, and from some ebay sellers.

Ikaw pala ang dapat naming takbuhan kapag may mga tubes kaming di mahanap, hehe ;)

Or you can ask the transformer winder that we both know for help on how to find tubes. (The tranny winder that is from Rosario, Cavite and a kumpare of your cousin, he does not sell tubes, but he knows some sources better than me.). ;D

Phasetron/Kinetic in Robinson's Pioneer

PS: What particular tubes are you looking for??

imagine U$1 tubes........ ;D

Just stay away from those "hustlers" that will tell you that Japanese tubes are better than Telefunken or Amperex!
I also had the experience of buying 12au7 tubes from a local seller that went bust after 3 months, and I bought it from a reputedly "honest" seller from another local forum!
Not only 12au7 tubes, I got some 6x5 tubes from a local seller that gave my preamp oscillations which took me a couple of months to isolate. >:( He also sold me some Siemens caps that leaks oil, upon checking, those old Siemens have PCB in them. :o Latak na yata ang binebenta nito.
The best insurance is to have the tubes tested before handing over your hard earned cash. In fairness, there are a lot of honest sellers. Get from those who are willing to give you warranty.

hello alex,
malas ka yata...dati na hazzle ka sa NOS....
daming triode pentode for sale at $1 like 6lu8 at 21lr8, pwedeng spud amp... ;D
-
primarily im a guitarist, so my knowledge of tube range from the 12aXX to elXX or the 6L types.
i have just explored hifi since i want to "upgrade" my home audio system.
i live in iloilo so tubes are a hard find. i buy my tubes from an old electronics store which sells some nos national tubes and some trigon tubes but he is running out of stock and his prices are a bit expensive.
id better look around the forum for more info.

Hi Tony,
Are you in town or in the place where they make the best vodka in the world? ;D
Malas lang siguro, or maybe I have the word "sucker" printed on my face. hehehehe.... :P
I heard from the "winder" you were in town a few weeks ago.

What National and Trigon tubes are available?
Am looking for EL84s and 6v6. Thanks.
If your source is running out of tubes, try ebay.com, or try tubedepot.com/tubestore.com, we had very good luck with these sources.

6bq5 ang sabihin mo, hindi el84. 6bq5 tatak sa box kaya di nila alam yun el84 hehehe
kasi alam ng watsons na dwindling na ang tube source...ubos na sa spin, sa southern mukang konti na rin.

There are a lot of honest sellers sa ebay, meron ding mangloloko.
I guess to buy at ebay, you need to develop relationship with the sellers, and avoid those first time sellers at ebay.
Kung mahal ang shipping, maybe organize a group buy, so that you will share the shipping expense.

i ordered 2quads of 4D32 at Surpluss sales of nebraska, very fast ang service, my order was shipped aug 12, it reached our post office around 30 of august...
i will order around 160 pcs of 1dollar tubes and shipping will cost around U$80....so 240 dollars will buy me 160 tubes for an average cost of 69 pesos per tube.....you can never find such prices here...
i am planning to do guitar amps...mahilig yung bunso ko eh..... ;D

there are other exciting tubes than the kt88, el34, 12axx's.....if you know what to look for.... ;D
as for me tv tubes, like the dissimilar triodes, example 6em7, you have 1/2 as 12at7 and the other half a small 2A3 with unipotential cathode, very linear...makes for a nice spud amp....imagine just two tubes and you have a push-pull amp....or a stereo SET amp.... ;D
heater variants are no problem, power traffos can be ordered from edrel sison, or if you wish, made to order at raon... ;D

HUWAW! sana may new generation TonyT's. parang "endangered species" na ang mga "tubo at tuberos" ;D
i just browsed my rca tube manuals, checked the "header" looking for power tubes. kontento na kasi ako sa 12au7 & 12sn7 preamp tubes hehehe
as for pre & power amp trannys, edred is The Man!
btw ok pa kaya podmon? (pang-budget projects hehehe)
-
hehehe...imagine horizontal output tubes (6BQ6) selling for 46 pesos!!! they are simply to cheap to ignore!!! ;D
there is a treasure trove in that list..... ;D
Podmon is the oldest, i have known Nelia since the early 70's....but there are other shops in raon that can do costum transformers at a reasonable price... ;D

Sirs,
Saan maka bili ng kt88. Busted isang tubo ng amp ko. Is it ok to change muna isa? O dapat apat agad. My amp is an int amp push pull.
-
^ from experience you would need to replace in Pairs to maintain coherence.
Tube source would be AMX(Andrew Sevilla) or Juanbote(Sir John).
Maybe Tony Tecson also has KT-88 on hand.

i have a quad of 6550 and kt88 but i am not selling them...
i got them second hand and i do not want to pass on a potential
problem to the next guy, i can not do it in conscience.. 8)
JJ KT88 are available here, http://epektos.com/product/2c40caf3-ea32-4546-8e12-f08fcc5eeb27.aspx
JJ's are a shade better than China tubes...
out of stock at the moment, but you can email them and ask them
to inform you once they replenished their stocks....
it took me a while to convince them to bring these tubes in,
and when they did, the stocks were gobbled up in a matter of a couple of weeks...
i am trying to convince them to bring in the 6SN7/6SL7 and the 5u4/5ar4 tubes as well...
we have the guitarists to thank for, they are the group that eats tubes for breakfast.... ;)

Sirs,
Saan maka bili ng kt88. Busted isang tubo ng amp ko. Is it ok to change muna isa? O dapat apat agad. My amp is an int amp push pull.
if i were you, i will try to find out first how come 1 tube got busted
before replacing it, at least a match pair will do...

I really want to know what is the brand that KT88 that got busted. NOS or new production? Is the amp fixed bias or self bias?

Sir Tony / Sir Jojo,
Thanks for the response.
It's a Cayin A55tp. Stock tubes. Actually pintatignan ko na kay Mang Rod and repaired. Kaya lang wala kaming spare ng KT88. Na try lang namin with a different KT88 (pero may ibang may ari e).
Nakak lungkot nga e. Ang ganda na ng tunog nung na kina Mang Rod na kaso wala ako spare na KT88.

Cayin used Shuguang tubes and fixed bias...the Cayin el34 quads i got in 2011 still lives today....

Ok let's not dwell anymore into the details of the repair since you already had it looked at by Mang Rod. I think it's fair to say that your amp is now ready to take in fresh tubes.
If I were you (and if I have the money), I'd stick a fresh matched quad in there and just reserve the other 3 good KT88s for later. If not, a fresh pair will do, preferably with the same brand as the original tubes you have now.
Wag ka na malungkot sir, palit tubo lang po yan. Life's too short, enjoy while you can. :)
Cheers

I see. I also have a quad in my collection. Those are hardy tubes indeed.

Just want to share this, it never fails to put a smile on my face every time I think of it.
There's this member here (I won't mention his/her name anymore) who has repeatedly asked me if just changing one (1) tube on a push-pull is ok... electrically, it is. But sonically, they should, at the very least, be replaced in pairs.
Ideally in a push-pull, the 4 tubes age at the same time, more or less, so it is prudent that you change ALL if possible (tube availability and funds come into play here).
This member was soooo "makulit", paulit-ulit lang ang tanong, parang hindi nadidinig yun explanation ko kung bakit sana, kung maari, sabay-sabay ang palit ng tubo or at the very least, in pairs. Para ba na ang gusto lang niya madinig yun sagot na gusto niya...
I think it's safe to say I have a huge amount of patience, however, I ended the conversation by saying this...
"Kung gusto mo magtubo, handa mo sarili mo bumili ng tubo. Nakabili ka ng tube amp tapos titipirin mo pag kailangan mo na magpalit ng tubo? Para ka bumili ng kotse, handa mo sarili mo magpa-gas pag may time, at hindi pwede kerosene ang ikakarga mo... otherwise, benta mo na lang yan at mamasahe ka na lang."
;D ;D ;D
Have a Blessed Holy Thursday everyone.

Maybe Jo he/she hasn't really got the answer he/she was looking for. But he really has great faith in you w/ these matters but just couldn't really get it. Like a patient who a doctor gives a clean-bill of health that he's perfectly find but keeps coming back to confirm that there is nothing really wrong w/ him. The doctor gives up & sends the person to a psychiatrist instead ;D
Now it really lit a smile on my face on a boring long weekend.

Try this guy Bingo Del Mar aka Sir Conrad he has a bunch KT88's. He's from here Cebu but you could ask him to ship it for you. Smart-09192863368 / Globe-09272910400 / SUN-09232393096.
He has also a thread here & in Wired state. GoodLuck ;)

I guess so, I did my best to not sound too technical, tried to explain it as best as I could but the truth is just too hard to handle. ;D
Maybe I should also brush up on my "art of persuasion" skills. 8)

in any case, he will have to bring his amp back to Mang Rod for bias adjustments, since fixed bias yung amp...
and yes, if he can find a seller willing to sell just one tube, (mahal kasi kung apat agad)
then that will work also, since adjustable naman ang bias....
the object naman is to put the tubes in the designed for operating point....
if that amp were mine, i will convert that to self bias, so that changing tubes will not require re-adjustments of bias pots...
the small loss in power will not be missed and SQ will likewise be the same...listening tests have confirmed this...;)
-
bias adjustment? madali lang naman yun, I'm sure you are more than willing to teach sir Ernel how to do that...
sadly it is not your amp so you can't have your way with it... BUT... maybe he can contact you and have his Cayin modified to self-bias so changing tubes can be easy peachy.
so fixed-bias or self-bias same na lang ang SQ? may I know kung sino ang nag test?

you can ask remington...

you can ask remington...
ah ok thanks
-
self biasing cost you the grid bias of the output tube,
like the kt88 where it will need about 30 volts, so this is subtracted
from B+ and so your output swing is lesser by that amount..
you lose a little bit of power that way, but to me the advantages
far outweigh the slight loss of power....

Car tire analogy would have worked. Manipis na 4 gulong at sumabog na isa, at least replace both front tires. O mas mahirap intindihin logic? ;D
-
rather than think tires, i will bring the other 3 tubes to watsons for testing and found out how much transconductance is left on the other tubes...
tubes may be near the end of their life and still work fine, but only thru emmision testing can this be known...
one tube failing may or may not be a sign that the other three are kalbo na, only thru proper testing can you know...
unlike tires, vaccuum tubes have more modes of failures that just wear and tear....

Absolutely. I use this analogy many times, but also to point out that in tires, 3 can be Yokohama, while the other one can be a Dunlop, as long as they have the same size and aspect ratio. Mas madali na intindihin ang logic, most get it in one pass... ;D

that is wishful thinking. most car users here don't even take their cars to tire centers for inspections. antayin muna yan sumabog o maging manipis bago palitan. meron nga kalbo na ginagamit pa eh, dapat pag kalbo na wag na yun gamitin kasi delikado na kapag kalbo.
unlike tires, vaccuum tubes have more modes of failures that just wear and tear....
they do have a lot in common with tubes... BUT, I'd leave it at that... baka mapunta sa vulcanizing ang usapan...

sir tony this is not about the tube...its a favor reg my 6lu8 amp...ngayon lang lumabas yung problem kahit na totally off na yung volume meron pa rin lumalabas na sound and i think nasa number 3-4 if yung potentiometer ko kung may numerical decals medyo malakas ^-^. do i need to replace my potentiometer i use a 250k...before wala naman siya, hum lang which di ko pa na naayos yung issue sa hum... ^-^ thanks sir.

dalhin mo sa house kung me time ka, most likely yung grounding ng pot mo yan,
if you can take a picture, send mo na lang thru pm...

Good PM to all.
I am thinking of changing the tubes in my amp - Cayin A-70T - the amp currently has KT88 tubes.
Hesitant lang ako to change tubes kasi may bias adjustment (?) pa yata na dapat gawin :(
I would appreciate it if you can help me understand this more and maybe give options how I can go about my plan?
Btw, sobrang bigat nung amp and mahirap buhatin but kung no choice for the biasing then I will do it.
Thanks again!
BTW, apologies if this is the wrong thread to post this. Thanks again!

you will need a small tip screw driver and a voltmeter, best to ask Cayin for instructions...
not that hard to learn....

Meron na ba naka order sa tube depot? how much inabot shipping and taxes?
Thinking of Gold Lion tubes if worth it.... thanks!

^^eh kung FedEx yan yari sa taxes...dala na ako sa Fedex..

^^eh kung FedEx yan yari sa taxes...dala na ako sa Fedex..
Ouch... yun nga katakot, minsan mas mahal pa sa item, making it parang "ndi worth the price" :(
-
magaling silang mag-imbento ng babayaran,
kaya ako pag nag-order ng tubes, binibilinan ko na
kahit ano mangyari, huwag sa fedex...
postal service lang okey na rin....kahit magbayad ako ng 500
hindi masakit sa kalooban...
