master..matangap ako sakura,open ko unit,sunog ang fuse .baklas ko lahat ang output..transistor para masure hindi na ulit sunog fuse,plug ko ulit ganun parin,sunog naman,chek ko diode ok naman po.mga master sakura sana matulungan ako salamat...

Ba swerte mo dyan dami tanggap.
Check for shorted components (lahat) muna sa power supply. Kung main fuse tanggal mo muna connection ng trafo sa PCB o chassis, baka trafo sira.

ka sis mag kahiwalay na ang supply shorted kc dalawang output transistor,akala ko ung dahilan bakit laging sibak fuse.pullout output trans,sibak parin..ok naman transfo,

measure mo muna supply baka hindi tama mga supply secondary check mo na rin kung may short ang mga circuit bago magkabit ng transistor ,, compair yung left and right channel

May mga shorted pang iba cguro dyan, Syempre sa amp output tranny lang, natanggal mo nman lahat diba? lahat. Dyan lang yan sa power supply, kasi yung mga smaller parts like opamp di kayang mamutol ng main fuse yan, sila mismo nag-oopen. Check mo lahat ng diode sa low voltage at higher voltage, regulators, at ecap.

agree check mo ecap madalas may prolem yan

baka naman under rated ang fuse nyo?
hang muna ac out ng trafo then plug at sukat ng ac out, to confirm na ok ang trfo

update nalang ako,rest muna, hehe,.salamat,

abeTIR · « **Reply #11 on:** July 13, 2011, 12:43:12 PM »

barado ang supply lines...usually shorted diode yan

Disabled · « **Reply #12 on:** July 13, 2011, 12:46:55 PM »

baka sa rectifier plang

hackerz · « **Reply #13 on:** July 13, 2011, 04:58:58 PM »

master at sis,pullout ko lahat cap/hindi pumutok ang fuse,

RhUNhA · « **Reply #14 on:** July 13, 2011, 05:02:33 PM »

bka nga out of rating yung fuse n nkakabit,,,check lhat ng parts baka may shorted,..

hackerz · « **Reply #15 on:** July 13, 2011, 05:07:00 PM »

10amp fuse sis,/4 cap/baklas kng laht,.pero sa tester hindi naman sira mga cap,..panu kaya eto.

Isa-isa mong ibalik ecap para mlaman mo kung alin ang may leak.

peyabu · « **Reply #17 on:** July 13, 2011, 07:17:48 PM »

hinugot mo ecap, di na pumutok fuse? nanjan ka na. malapit na.

hackerz · « **Reply #18 on:** July 13, 2011, 08:16:10 PM »

tama mga sis isa isa kung binalik.ung isang cap ang salarin..kaya pala sibak fuse,sa tester hindi malaman kung sira na.anu bayan.?

RhUNhA · « **Reply #19 on:** July 13, 2011, 09:39:44 PM »

plitan m na ng bago pra mlamn kung mag ok n ang unit mo...congrats n..
