Topic: SAKURA AV-200T Tube Amp

[rochie]

Planning to move the Sakura amp into the dining room.  I'd like to attach it to a cheap source.  Someone gave me one of those no-name Android tablets with an SD port.  Thinking I can load music onto an SD card and use that tablet as source.

Anyone have any experience doing this?  SQ?

Or, are there any cheap media players I can use to play just audio?

in my experience mas ok ang SQ ng portable audio player ko before(sansa clip+ and cowon j3) compared to my android tablet/device(kindle fire/htc desire hd).so baka sir meron kayo lumang ipod na hindi na ginagamit mas ok gamitin yun compare sa mga unknown/china brand na android tablet.

hehe... nice one sir jojo...

mga boss,  ano kaya problema ng sakura ko?  bigla na lang nawala yung buong buong sound nya habang nagpapatugtog ako.  bigla na lang naging puro kalansing at tunog lata output ng speakers ko?   

wala na kasi yung resibo nito at ayaw na tanggapin sa binilhan ko when i called.   pinacheck ko sa pinaka malapit na technician sa amin.  binentahan lang ako ng mga 2nd hand amp nya.   di na daw narerepair mga ganito.   

any idea kung ano pyesa nasira dito?  may output pa naman sya nag power on pero yun lang tunog lata ang lumalabas.

ot:
am not sure if you can install an external dac on your tab. you can probably get a fiio e10 dac to pair with it so it will sound smoother and cleaner. 2nd hand might cost you 2k+

there's a sakura at deeco ever commonwealth. i saw 1 last week.

both channels po ba? paki silip nga po kung nagbabaga ang mga heaters ng mga tubo? pwede kasing nawalan ng supply yun plate or yun heater ng amp ninyo.

hi sir jojo,  thanks for the reply.   yes sir, umiilaw yung mga tubes nya.  napapansin ko din, pag power on, umiilaw yung power button sa harap pero parang hindi umaandar yung fan nya sa likod. 

[JojoD818]

may malaking chance na isa po sa mga power supply ay nag loose, nasira o nasunog. mas maigi po talaga na ihanap niyo ng manggagawa para ma-repair... or baka pwede niyo track down yun service center ng Sakura dito sa atin.

and fyi po nun pinakamalapit na technician diyan sa inyo, na-re-repair naman po yan, baka hindi niya lang alam kung paano...

Good evening po! Newbie palang po ako sa sounds. Ask Lang po sana ako ng opinion regarding sa nabili ko na Sakura av-200T kanina sa Deeco sa sales st. Manila. Pag uwi ko po ng bahay ay sinubukan ko kagad yun bnew tube amp na nabili ko sa turn table ko pero napuna ko po kagad na mahinang mahina ang volume kahit na isagad pa ang volume level at parang di gumagana ng matino yun amp pati tunog. Ano po kaya ang problem? Yun tube amp unit po kaya ang may problema? Balak ko po ibalik kaagad sa Deeco bukas para sabihin ang problem. Salamat po sa tulong in advance

[eliahp]

Got myself Sakura AV200 din kanina lang at Deeco. For its price panalo na din ito for a decent set-up.

@Aav888
Baguhan lang din ako in this kind of hobby pero palagay ko kaya di maayos yung tunog nyan dahil kailangan mo pa ng phono stage? Im not sure though sir, opinion ko lang. HTH.

Lets wait for the masters input here.

you need a phono preamp. hanapin mo si rene rivo, meron syang mods para sa phono preamp input.

   thanks Sir Jojo.  Hirap lang talaga pag sa province.  unlike sa manila, kabila kabila mga shops at mga service centers. 

[simplekryz]

3k sir parts and labor na.

boss pwede mag order ng av-200t modified kindly txt me 09266553161

   thanks Sir Jojo.  Hirap lang talaga pag sa province.  unlike sa manila, kabila kabila mga shops at mga service centers. 

You're welcome sir. Madami na din ako na-repair na av200 and usually it is psu related or busted outputs. Hanap na lang po kayo ng manggagawa diyan sa may inyo sir.

boss pwede mag order ng av-200t modified kindly txt me 09266553161

sir afaik hindi na nagmomodify si diy_master ng sakura dahil super busy sa speakers, and 4 years ago na po yung quote nyo na post nya

[ATJr.]

^rene rivo is selling a modified one with phono stage for 8.5k....

[Gino]

Kung bag amp no baka pwede trade in and pay for mods. Pm Hyper audio. Si Rene Rico si Hyperaudio.

[ATJr.]

Rene Rivo is the man....

[buchieboy]

Newbie here guys and in need of help. I currently have a nad 325/515 and wharfedale 10.1 combo which i find dark sounding (good for some recordings but not for all) will a modded (by hyperaudio) avt 200 and pairing it with the nad515 and wharfe 10.1 have better sound quality?thanks!

[Gino]

I interpret dark as thin sounding. You are struggling to see an image. Thin sounding pa din ang Sakura. Pero due to tube harmonics, namamaga ang tunog. I liken this to the BBE effect of the 90s. What you hear is different and maybe pleasant but it is not added detail. It is coloration.

how do you plan to pair the av200 with a nad515?

sir tony yung nad515 ata cd player.

You have already a good combo with your NADs, what is dark for you? Limited highs ba, you are looking for highs(kalansing) in your current set-up? I wonder if you have considered to test/hear other speakers.

[buchieboy]

@ndotcom : yup im looking for more treble extension, clearer/faster lows. I also find the nad/ wharfe set up to be too upfront with vocals that other instruments are left behind.

Will a speaker change address the concern?

@ATjr. Nad515 cdp wt d sakura amp

Thanks for the help!

[fishda]

i suggest you bring your speakers to the shop of sir rene. he'll be more than glad to assist you with your auditions:) then let your ears decide.

[ATJr.]

in case you missed the technical descriptions of this AV-200, i will run them again...

there are 4 tubes on the chassis, 2 x 5Z4 rectifiers and 2 x 6N2 twin triodes..
the 2 5z4's are rectifiers that supply rail voltages for a rc4558 input buffer ic...
the output of these rectifiers are zener regulated at 6 volts...
the ic drives a tone control circuit with another rc4558 in active configuration,
this other ic however is fed rails off the power amp board via lm 7812/7912 regulators..
the 6n2 tubes are also fed off the regulated +-12 volt rails, configured as a cathode follower,
as we all know, cathode followers are 100% negative feedback circuit with voltage gains around 0.9
this and the use of tone control necessitates use of the rc4558 integrated chips..
cathode followers are not supposed to "color" the sound...
but the fact that very low voltages were used on a tube that needs significantly highish
voltages in order to be in the linear region, then this coloration happens...
the av200 represents a break with all tube design traditions that only the chinese can do...

incidentally, just about any type of b9 tubes ca be tried, i used the russian 6n23 in mine...

btw, Chino's sakura av-400 is much better than the  av-200 in terms of power, owners of these units are advised to hold on to them...

Newbie here guys and in need of help. I currently have a nad 325/515 and wharfedale 10.1 combo which i find dark sounding (good for some recordings but not for all) will a modded (by hyperaudio) avt 200 and pairing it with the nad515 and wharfe 10.1 have better sound quality?thanks!

I have one (modded by Rene Rivo) and its not the right amp if you want to remedy that dark sound. The only tube component of the AV200t is it's Preamp section and the power is still SS. Its a good amp for laidback listening as the Tube filtering renders music to be more warm and musical, its a step up from unmodded AV200s (a very nice step up too!) but it's still a tad dark. Wharfes are power hungry in my experience so the AV200's 20W/Channel output wont really do it for the 10.1's (yup it's just 20-25W; dunno why they claim it to be 200w as my friend measured it).

That being said, Rene's AV200 would be ideal if you're a newbie to Vinyl and Hi Fi as it has a Phono In, Sub Out and 2 extra inputs so you can experiment to your heart's content.

Plus the tube coloration renders most mp3 to be really listenable. Tatagal ka makining kahit mp3 lang source. IME it lessens ear fatigue because of said coloration.

FWIW look for vintage Sansui INT amp with a high watt rating. These amps are really detailed and bright without being grating and can properly drive your wharfes on the cheap.

Just my two cents

They have a website: http://sakura.com.ph/

Maybe you can start looking there.

sa Eton (tapat ng Robinsons Galleria).. Crown ang name ng store, I inquired before about this amp, and asked yung sales lady na what if magka problem ang amp, sa kanila lang daw dalin
