Topic: SAKURA AV-200T Tube Amp

[George SJ]

I have sakura av200t. it preforms very well. i hope this can answer all the questions i've read. first, mahal sa deeco. 3990, mas mura sa tapat ng deeco. i got it 3500. mabait pa ung chinese guy and he has the direct contact with the factory of sakura. maraming lumabas na fake sakura tube. ung chinese na kausap ko may paper na authorized sya as dealer and pwede syang magreport sa lahat ng fake sakura. Walang pwedeng gumawa or mag-ayos ng defective sakura sa raon. puro simple remedy lang ang gagawin nila. ang sabi ng dealer, kukunin nya muna ang unit at ipapadala sa factory kahit masaira ang tubes. Yun ang dapat na makausap nyo. baka ang nabilhan nyo ng sakura tube amp ay hindi registered.

Correct also sa sinabi ng isa natin member na from 30-40 watts lang sya. hybrid amp. hindi talaga na maximize ung lakas ng tubes. And in terms of A-Audio or si sir anthony ang may stock ng tubes, (correct me if im wrong) si sir anthony po ay pwede mag-modify ng buong sukura tube amp. nag-tanong na rin ako sa kanya, and sabi nya, mga 20 percent ang pwedeng i-ganda pa ng sound sa mga modifications na gagawin nya.

For 3 months of break-in, ung pang third month makikita nyo ang difference. As in! But try to have a decent BS speakers. I jas bought my D1 speakers last March 12 kay sir anthony, you know what? it really performs well. malalim ung bass, the mid-range and tweeter, perfect! timplado. i placed the volume at 7 o'clock for i week then  8 o'clock in this second week. With my estimation. Sakur can drive speakers from 30 to 100 watts. dont ever use it in a much higher watts coz it will only disappoint you.

ung isang question naman about more than one inputs. its already my 3rd day using Sakura tube amp with my turntable and cd player. I jas realized if both the cd player and the turntable is playing, there's a little hum. example: im playing my turntable in the cd slot of sakura, so before you switch the sakura selector to dvd ( which is playing an audio cd) you will lower the volume di ba? so ginawa ko yun until its off. i can still hear a song humming at the speakers before i turn the selector to dvd from which my cd player was hook.

hindi ko rin malaman kung bakit may feedback na ganun. kung talagang magaling din ang gawa ng Chinese, sana nakita nila ung dilemma nun.

imo, hindi sya amp made for karaoke purposes, unang-una low wattage lang sya, around 20watts rms or lower pa ata? 2nd wala syang microphone in.  merong konzert 502 na for sale sa market place, yun pwedeng pwede pangkaraoke brader.

[oweidah]

sirs, tama ba ang title ng thread? tube amp nga ba ang sakura av200t? para sa kaalaman ng mga newbies like me thanks po

ngek, kaw pa Sir Rene 

[oweidah]

solid state amp ito na nilagyan ng tubo.....

i wouldn't even call this a hybrid, walang kinalaman yung 6H23 sa power amp section, ginamit syang buffer circuit....

thanks, o ayan mga newbies...hindi de-tubo yan!

ngek, kaw pa Sir Rene  

   

[supermanster]

pwede yang balak mo, lalo na kung meron ka ng av200, pero kung wala pa at bibili pa lang, yung electown na 502, P2,950 sa deeco mdron ng mic input pang karaoke...

Salamat po sa mga sagot mga masters. Actually kabibili ko lang po kahapon kay Sir Anthony ng modified Sakuras, kasabay ng D1 at Videoke speakers. Plano ko nga din talaga bumili ng Konzert502a amp dedicateds sa karaoke kaya lang baka sakaling umubra din itong sakura na nabili ko since amp din naman sya. Anu po kaya ang magiging disadvantage nito kung sakaling gamitin ko siya as Videoke Amp? madali kaya sya masira kumpara sa 502a?

supermanster,

pwede yan gamitin bilang amplifier, pero dapat sa gagamitin mong dvd/videoke player ang microphone input.
ganyan ang ginawa ko. tapos i-hook mo ung videoke speakers that you bought from anthony. tapos sa audio settings ng dvd player mo ikaw mag-adjust ng echo, equalizer, etc. until you appreciate the sound quality...

Mga sirs,

Would anybody know if this sakura is bridgeable? Has anybody tried to bridge this amp?

Thanks in advance.

[George SJ]

thanks sir tony. kahit papano, tumunog ulit ang sakura.

[jay2]

sir tony yung av-200t ko bakit yung isa channel mas mahina ang tunog kaysa sa right channel? I have tested it only once a few months back then naitago ko na ok naman sya nun then pinaandar ko sya kagabi nung umpisa walang left channel pero pagnilakasan ko volume nagkakatunog naman mahina nga lang. Binaligtad ko na rin ang input baka kako yung cd player pero ganun pa din.

[Schrodinger's cat]

Sir Tony, replacing the 6h23 with other tubes won't alter the sound much right? not worth tube rolling? I have extra 6n1 tubes kasi, can I use those in place of the 6h23?
Iba pa ba yung 6h23 sa 6h32?


Thanks sir  

[George SJ]

sir tony, meron pa ba tayong dapat gawin sa loob? as what you've posted...

possible replacements for those peanut tubes:

6922, 6DJ8, 7DJ8, 6BQ7, 6BK7, 6H23, ECC88, etc.

to avoid the tubes getting busted as in the case of MajorKonig, the unterminated pins should be soldered to the corresponding pins of the active half...

filaments are in parallel so there is no way to turn off the filament of the unused half, meanwhile cathode poisoning is a real possibility as what happened to George's amp.

of course simply replacing the busted tube is easy.....

Hi Sirs,

I'm having the same problem as stated by sir jun2 above. Is there anything that can be done to fix this and is it worth the trouble of having it fixed at all? I have been using my unit sparingly and usually at low volumes, I'm wondering what could have caused this.

Sir TonyT, do you still do modifications of this amp? Been reading back on this thread and I found out that you do some mods on this amp. I wonder if I can bring my amp to you for repair of said problem and modification too?

Thanks.

[cm8]

ok you can bring your Sakura's to my place for some check-ups...

Thanks Sir TonyT. Will PM you when I have the time to bring it to your place.

[tein]

Hi sorry can't back read na super bagal kasi ng pocket wifi, just wanna ask guys kung sinu pwede mag mod ng sakura namin for our store please PM me nalang how much. We are using kasi that amp to drive our demo speakers  Thanks masters 

[princess salina]

Mga sir newbie question po, i just recently acquired a sakura av-200T, my first taste in tube amps. I noticed n ung left side n tube  mas maliwanag ang glow nya kaysa s right tube,although parehas nman ang output sa speaker btw i'm using wharfdale 10.1, is it normal po ba or my problema sa tube,so far maganda sq ng sakura clear ang vocals.thanks mga master

[Nelson de Leon]

this is not strictly a tube amp, but rather a "tubed" amp.....the speakers are driven by 25watter solid state amp, jojoD's baby G has more power....

do not pay too much attention on the tubes, eye candy lang ang mga yan.....

Parang buffer lang siya?

[JojoD818]

yes, cathode follower yung 6N2 tube,

ok ito, parang Joe Rasmussen ang principle..

supply naman ng 4558 ic yung 2 5z4 tubes...

ito naman lame hahaha... magkaroon lang ng gamit yun mga rectifier tube. sabi nga sa kabila, "grave misappropriation of parts..."  



EDIT: pero sabi nga nila, walang basagan ng trip - yan ang trip nun designer eh so let it be... baka naka-inom ng Tsing Tao beer habang nag design... peace!

thanks sir TonyT

[docrob]

i'm interested in this amp i really liked how sir Tony described it:

"that is why this amp is a DIY'ers friend....lot to tweak, lot's of possibilities, limited only by one's imagination"

and he has enumerated the lists to be modified also, so pwedeng project sa future

he also said:

"the Sakura is a low cost amp that delivers the goods.. ...i bought the amp because of its novelty and the fact that it gave me more value supplying me with spare tubes.....

spending more money than what is cost you to acquire the amp is not a wise imho......"

talagang malaking bagay ung price nya na affordable talaga

sir monreq and sir Jojo and others have provided good insights as well

After reading what has been said, discussed and discovered (both good and bad) about this amp would you still recommmend it? Is it good enough in stock form?  if ever kasi i would like to enjoy and familiarize myself with it's sonic qualities first before modifying it?

hoping for some responses

thanks

[JojoD818]

Audition, if you like it as it is, then go get it. It's your hard earned money so you have to like it to buy it.

I think you'll be able to test it in some shops in Raon area.

Good luck sir!

 

[tein]

Bilis nito mabenta sa shop !

Sakura AV-200T powering the Duevel Planets 

[docrob]

thanks for the replies,aal are appreciated


sir Jojo you're right, why buy it if you don't like pinamigay mo na rin ung pera mo kung ganun. medyo mahirap lang magtesting sa Raon at maingay ung place pero kailangan before buying

sir tein, nice gear you have there.  me shop ka ba? available ung amp?  thanks

sir Tony, the "cheap" price is really it's selling point kaya nagkainterest ako.  thanks for the tips vet helpful talaga

hope to hear from the others, too

[docrob]

sir Tony, what do you think should be done to the ecaps you mentioned?  thanks

[markcrenz]

sir Tony, what do you think should be done to the ecaps you mentioned?  thanks

i'm guessing replace with poly caps. or install poly caps parallel to the ecaps, value about 1/100th of the ecap.

[docrob]

wow,  wala ng matitira sir Tony?

i'll start with the basic mods muna siguro after familiarizing with the characterof the amp, then ask na lang for help pag mahirapan ako
