it could any of various things, could be a loose ic, etc...
how old is your Sakura? was it like that when you first bought it?
i heard a story from one who bought it that there was a thump when first powered on,
and several units tried were like that, so what he does is not connect the speakers
until some time has elapsed, and i say it shouldn't be like that at all...

1 1/2 years I suppose, I got it as a second hand item. The thump is manageable considering that you need to wait for 3 to 5 seconds before connecting the speakers.

The only thing that I need to have this unit serviced is the grounding system.

thanks..

nakakita ako ng Sakura AV200T sa instagram feed ko.
namiss ko bigla yung AV200T ko, i think so far yun yung best amp na namatch ko sa Celestion 9 ko.

Sakura AV200T -> dual SMSL 36 -> single B&O ICE amp. malinis tumunog naman lahat, hirap yung SMSL, pero kaya naman at reasonable levels. for some reason, mas malambing lang tumunog talaga yung Sakura.

sa mga nagtatanong ng bagay na speakers for this amp, try niyo yung Celestion 5/9.

with the proper placement, you'll get good enough bass extension.

madali lang ba patayin mga LED light nito? para puro tube lang umiilaw? parang mas ok tingnan yun

@Sir Tony, @Sir JojoD

Sirs, Possible ba to convert this amp into a pure tube amp?
If Hyperaudio managed to do some mods in the amp baka posible din na i-convert this amp into pure tube.
Just use the chasis etc.

Thanks

tony · « **Reply #994 on:** May 28, 2014 at 10:27 AM »

^converting that to a pure SS amp is more viable...
Rene added an ic phono stage to the Sakura...

the two peanut tubes are cathode followers, not really needed....
the two big rectifiers supply +-6vdc, can be done with zeners only
as it is already there, tapping from the +-15 which is regulated is easy...
the tubes in the Sakura 200 are there as eye candy....

To the users of this amp, is it possible to use a tablet as its player of lossless music files? If yes, how did you connect it to this amp? Finally, any chance a Blackberry Playbook would work in this kinda set-up?

Thanks.

^^maybe a 3.55mm (via headphone out) to RCA interconnect will do?

How would the quality of the sound be compared to a USB connection as regards other gadgets/equipment?

Thanks.

panzimus · « **Reply #1000 on:** Jun 05, 2014 at 10:59 PM »

that would depend on how good the built in dac of your tablet. if you could use an external dac in between of your tablet and amp, that would be better.

Cool. What can you suggest as a budget DAC that would perfectly blend and work well with that setup (Blackberry Playbook > DAC > AV-200T)?

I have this moded AV-200T bought from sir Anthony i thinkg mga 2-3 year na together with A-Audio Bookshelf speaker. Di ko sya nagamit dahil sobrang busy at mas gusto ko manuod ng movies plus hinde ako maka timing sa Market place ng decent CD player.

Nung isang gabi I decided kuhain sa baul yung AV-200t at yung bookshelf speaker. Ni hook ko sya sa PLatinum BMB-one karaoke namin. Akala ko sira na yung amp kasi nun una ayaw tumunog pero umilaw naman yung mga tube sa gitna. Pinagpalit palit ko lang yung connectors at yung selector knob and then ayun nagulat ako biglang tumunog.

Nagtest kame ng songs at videoke songs at maganda pala sya tumunog

Here is the actual photo of the set-up, parang yung Bmb-One na ang magiging cd player ko nito.

Haha, sa totoo lang sir nalimutan ko na. Isa sa mga collection ni si Anthony yan eh pero diko na maalala exact model.

Main purpose ko talaga dati is to set-up a Music/Audio set-up para sa small room ko. Kaya yung kinuha kong BS is for that purpose.

May amp ako na ganito and looking for a suitable BS... ngayon lang ako nagsisimula sa Hifi hifi na yan eh..

Good day to members and masters....

I have been reading this thread from page 1, and am seriously considering purchasing one this coming Sunday (SWMBO gave the green light ^__^).

I just want your inputs please. I currently own a HTIB from Philips (HTS3366) but the player/amp got wet during habagat last year and it stopped working. I still have the speakers and my plan is to connect the 2 speakers to the SAKURA AVT 200. I also want to connect the passive sub, but I'm not sure if it can power it up. Here are the specs of the speakers..

Loudspeakers
Satellite Speaker: 2 Floor standing pillars
Satellite speaker drivers: 3" full range woofer
Satellite speaker impedance: 3 ohm
Satellite speaker freq range: 150-20000 Hz
Center Speaker: Magnetically shielded, 3 way
Center speaker drivers: 1 x 2" tweeter, 2 x 2.5" woofers
Center speaker impedance: 6 ohm
Center freq range: 150-20000 Hz
Subwoofer driver: 6.5" high efficiency woofer
Subwoofer impedance: 6 ohm
Subwoofer freq range: 40-150 Hz
Subwoofer type: Passive

The plan is to get the tube amp and connect the 2 speakers + passive sub. This will be used in a small room, roughly 20 square ft. for 70% music and 30% movies.

This is my first post and thanks in advance!

Copy Sir. Thanks for your prompt reply. Currently this is my set-up. Makakatulong po ba yung subwoofer para mag improved yung output ng system ko?

the Sakura has a mono low-pass filter that combined the left and the right channel lows into a single channel,
this is just one option, most powered subs lets you connect the speaker terminals into it, another option...

you need a powered sub...

supermanster · « **Reply #1012 on:** Jun 11, 2014 at 02:40 PM »

Konzert KS-8W powered subwoofer, pwede na po siguro eto? Ayaw ko po kasi masyadong malakas, nakakahiya makabulabog sa kapitbahay. Pang Home/personal use lang naman namin. Tsaka mga 2-3K lang budget ko for a subwoofer.

Mga sir anong tube ba yung 2 maliit na gamit ng sakura sa av 200t? 12ax7 ba? Hehe if not ano sya and ano dn pwedeng alternatives pang tube roll!

TIA

tony · « **Reply #1014 on:** Jun 15, 2014 at 06:17 PM »

ecc88, e88c, 6N1p, 6N23, 6dj8, 7dj8, 6922, CCa, 6bk7, 6bq7...
yung original na 6N2 equivalent to 12ax7 pero 6 volts ang filament so hindi pwede ang 12ax7..

as it is already there, tapping from the +-15 which is regulated is easy...

sir tony...judging from this revelation...then the tube doesn't contribute at all to the SQ of this amplifier.

in short its a fake...isn't?

yes, the tubes in that amp are for show only......
but even so, the price of the amp is hard to beat
and some folks actually enjoy the sound....
i was able to get rid of the 2 big tubes in one of my mods...
i was about to get rid of the small tubes,
pero nahingi ng bayaw ko kaya hindi natuloy....
one day i might just be able to do that...

Thanks for the reply...i was on planning to get this sakura amplifier after reading the whole thread. But when i read your post on how this vacuum tube were included in the circuit design...uhmmm...i will think again.

sir tony...so how's the VT PCB layout, can it be modified to act as an preamp stage?

it is a preamp stage with 2 op amps....
it can be modified to get rid of the 2 big tubes easily, all you need are just 2 resistors.

KALUIT · « **Reply #1019 on:** Jun 21, 2014 at 11:53 AM »

Sorry sir tony, what i meant was...to act as preamp? not just a decoration on the preamp stage.
