check driver, hung mona lahat ng output tapus sukatan mo ng voltage dapat pari-parihas ang makukuha mo kahit + at - basta pariho ng reading

makitambay nga..agree sa mga master

mga sis pa ot.. bigyan ko lang kayo ng points para sa mga utang ko yan..

TS sundin lang payo ng mga master at kapehan na yan.. basta be sure sa pag kabit ng mga trannie dahil meron jan na hindi dapat naka dikit sa ground.. check nyo narin mga fusable resistor at pati ung mga diode nyan..
goodluck

sis taquinaga...+1 sis pete,,,+1 ung untang ko pala points para sa n u...try ko advice nyu 2nyt....

mga sis na check ko na ung output xsistor mosfet ung gamit nito 2SK899 at saka mga driver trannie,,wala naman akung makitang sira,,,d nga palang aku ng voltage check,,,sis ok lang po ba e power on ung amp. na d ikabit ung output nito? for voltage checking purposses. d ko kasi na try to.

Testing ko ito mamaya,,,kong meron na po bang changes kasi galing to sa ibang tech. kinabitan ng jumper ung fuse.

taqui · « **Reply #15 on:** April 20, 2011, 08:34:44 AM »

yap pwde yan, for safety narin ng output, baka brigde diode sira nyan ha..

x13r_kit_0 · « **Reply #16 on:** April 20, 2011, 08:42:17 AM »

wala na po ba kayo natrace na shorted...
check for bias voltage...for sure na hindi masira ang output mo.

RhUNhA · « **Reply #17 on:** April 20, 2011, 08:59:39 AM »

ok nga kung hindi m muna ikabit...pero ok kba tlaga n buo yan...yung bias voltage check mo kung n5551 ginamit direct plitan mo na...

Meron sis, meron nga n5551,,,ok bali aku ngayun ng ma testing ko mamaya..
