yun kasing natry ko lately latest revision din, wala namang ganyang issue...
try mo i zero ang volume, then unplug mo all input connections,
then i off mo, tignan natin kung me pinagkaiba...

ibinigay ko yung sakua tube ko sa kapatid ko, preparing to have tube amp again, any low cost recommendation, my speakers are 50w and 100w rating.

san meron nag latest version nito at paano mo malalamang latest version nga?

tony · « **Reply #1142 on:** Mar 24, 2015 at 11:47 AM »

kahilera ng deeco sa raon........and to make sure, we have to open the bottom plate..

the earlier models, uses a speaker delay relay, (orange in color)....with #15 sticker..

the latest model i have opened up, notice upright modularised board, and the absence of a speaker delay relay...

Ang workaround ko sa ngayon for the turn-off pop sound is to use an extension/power strip na may mga individual switch. Imbes na switch ng amp ang gamitin ko yung sa extension na lang papatayin. Ok na yehey

Interesting, will try this out. Would this wok with an AVR?

songerph · « **Reply #1147 on:** Mar 28, 2015 at 03:11 AM »

Works with an AVR or any switch other than the amp's. I guess yung issue nga ay yung power switch ng amp. Baka may nangyayaring science somewhere there. XD

bosyo · « **Reply #1148 on:** Mar 28, 2015 at 06:10 AM »

solutions

1. turn off connected devices to rca input/output then unplug to the wall socket.
2. turn amp volume to zero and off.
3. use different wall outlet for each devices

works well for me.

may marking din yung power cable nang amp
kung ano ang left sa wall outlet
nagtataka nga ako pag nabaliktad may pop sound

SAKURA power !!!

good to know you found a work around,
i also use a power strip where all my gears are connected,
all the gear's power switch are in on position so that only the power strip
switch is turned on or off...

others who are having the same issue can do this...

Just tried this for the first time this afternoon, it worked, No popping sound if I use my AVR's switch instead.

congratulations, other members can not have a fix as well...

how about the same amp without the tubes?

i am working on one and have removed the big tubes at the back,
next to go will be the two small tubes in front....

i hope i can do it before your next EB...

sso this would make the Sakura amp a pure solid-state amplifier without a tube buffer, tama po ba?

lahat....getting the buffer out out fo the loop saves you 4.7uf in the signal path...

pansin ko hindi umiikot fan sa likod ng amp ko kahit 3 hours nako nagpeplay ng music at med-high volumes tapos mainit na yung amp. haha naku

songerph · « **Reply #1161 on:** Apr 09, 2015 at 05:42 PM »

parang pinapasok ng maliit na langgam. bakit kaya?

tony · « **Reply #1162 on:** Apr 09, 2015 at 06:54 PM »

dapat yan iikot ang fan pag me signal sa speaker at hihinto pag tigil ng music...
so kung hindi ganyan ang nangyayari, pwede mo ibalik sa kinuhanan mo para macheck-up..

songerph · « **Reply #1163 on:** Apr 09, 2015 at 11:37 PM »

i see. binabantayan ko ilang araw na. hindi talaga umiikot lalo na kung sobrang init na. mukhang ibabalik ko this weekend.

songerph · « **Reply #1164 on:** Apr 10, 2015 at 12:23 AM »

ayun umandar na uli hahaha. yung reaction ng fan depende sa output.

kapag tv series or pop or classical music hindi nagrereact yung fan.

kapag malakas talaga ang volume at matindi ang bass (double peds, metal genre) umaandar yung fan. haha.
kapag movie na matindi ang barilan or may explosions umaandar din yung fan.

LOOK MA, NO TUBES........

this is my final hack for the Sakura AV200...get rid of the tubes, we don't need them anymore.......
so don't be afraid if your tubes dide out on you, the amp can still run...

program source is my midi player Bread was on deck...

panasonic 2,2ufd polypropylene cap inserted at pins 2 and 3 on the 6n2 socket...

first tried out a 10ufd cap but leads are not enough long to fit into tube socket

a tube ss rectifer can be used also to get rid of the 5z4///

Tube Exorcism completed....
