Topic: SAKURA AV-200T Tube Amp

[TOP 20]

May I ask if there's an old fashioned volume pot that can be a viable replacement for the modded AV-200T?

Rene Rivo replaced the stock volume pot and it's working perfectly except that it kinda misses in between loudness levels.

I listen at moderate levels, mga 6 clicks or turns of the volume knob. Pero merong mga CDs na malakas na for me at that level. Now, when you turn it down a notch, sobrang hina naman.

I really prefer yung pag pihit walang clicks para ma achieve yung desired level.

Any tips?

Sayang naman ang pot kung papalitan, I'm almost sure magandang quality yang ikinabit ni Rene. Yun nga lang di tumugma sa gain structure ng amp. What I can suggest is to place a passive attenuator, around 6dB, before the pot para benign lang ang effect sa SQ. You can then dial in to your desired volume level with a larger turn of the knob, say yung 6 clicks mo would be 12 clicks na, and 11 might be the sweet spot. Hindi ito pwede if sa orig 6 clicks halfway na ang ikot ng volume knob.

The best guy to solve that is Rene.

yes, and i wouldn't out of respect to Rene's stature make comments, you should let him fix that for you...

Thanks for the advice guys.

I'd pay Rene a visit on a holiday one of these days. The traffic along Osmena is the only thing that's stopping me.

Cheers bros!

Tsaka wala naman yatang sira to fix. Its more of a preference for bro Top 20. Ganyan talaga tayo na may sakit sa audio. Always looking for that sweet spot between our gears and listening preferences.

Yup, nothing wrong with the amp and the volume pot bro, except that I kinda feel it misses that "imaginary" softness / loudness mark. Nasanay yata kasi ako sa mga volume knobs ng mga lumang amp.

[Gino]

That is a valid concern. You shouldn't live with it. Find the time. That can be sorted out.

Sakura with phono stage....
this version of the sakura is latest one i think,
no speaker delay relay but then no turn-on thumps,
a big improvement by the Chinese...
the power amp section has 3 boards mounted vertically
a departure from the early models...surface mount
components are used in these boards...it can only mean that
they are making this amps by the thousands....

[docrob]

ok yung newest version ng sakura amp with phono stage na ah

how much going price ngayon master Tony?

That's because it's cheaper to use linear pots rather than audio taper ones. Ang problema lang, biglang lakas - then biglang hina. All Sakura amps and their counterparts/rebadged versions use this.

Ang sabi nun supplier, it gives out daw the illusion of being "malakas", kasi kaunting pihit mo pa lang daw malakas na. Ang sabi ko naman, kaunting pihit pa - basag na. Di naman daw inaabot yun ganun kaya walang nagrereklamo.

Kaya nga mababasa niyo yun ibang amps ng Sakura are advertised to be matched with 400W to 500W speakers. So system matching din ang tinuturo nila.

In fairness, yun mga videoke machines na for rent ang lalakas ng mga tunog, yun iba nga naipapa barangay pa eh.

I see, husay talaga ni master Tony

I hope you don't mind but do you plan to offer that option to sakura owners, sir? Thanks

[docrob]

from me.....

yung phono stage mo, pwede gamitin sa ibang amp o pwede kong ilagay sa isang box with input/output terminal with correct power supply?

My AV-200T Left channel got busted, no sound at all,  I replaced the 50K potentiometer with a 100K pots but seems too much attenuation so I put an original 50K rating.  Result is now OK and back to original placebo effect tube sound.  Still satisfied with my AV-200T paired with a DIY local brand 40watter FR speaker.

Hello mga sirs, ask ko lang what is the possible cause bakit bigla na lang di na tumutunog yung av200 ko. Bago sya nawalan ng sound may naamoy nako sa amp na amoy sunog. Nkailaw naman lahat ng tubes. Almost 6 months palang sakin yung amp. Salamat sa mga magrereply.

[Superman]

Bro, baka transformer. Is this stock or modified?

under warranty pa yan, ibalik mo sa binilhan mo for after sales service...

[nicky]

Naiisip ko kasi baka tumagal ng months bago bumalik. Kasi kaya ko din nmn magpalit ng component kung malalaman ko kung ano papalitan. Pero tama ka sir tony balik ko na lng under warranty pa naman. Salamat.

[bosyo]

so far wala pa naman problema ang sakura ko. tulog ko lang ang pahinga niya

even if that happened to me, i will still bring it back to where i bought it, because that is the right thing to do....

^the Sakura has more power than the AMX tube amp, and the bass and treble control lets you tailor the sound to taste....
