ugong..... lang maririnig ......??????
« on: May 03, 2012, 06:55:36 PM »
patulong po mga sis may natanggap po ako amplifier ugong lang po maririnig pag power on mo ugong lang ito po yung unit pic

una ko ginawa tinanggal ko yung equalizer section...  power on ulit ugong parin
pangalawa...check component...shorted po yung power amp naka red circle saka po yung trasistor ..sunog dn po yung mga reistor
dn,...... pinalitan ko po yung mga defect component
power on ulit without equalizer ugong parin  paki edit nalang po sa guide thanks.....

   


NEWBE LANG PO>>>>>>>SALAMAT

remove output (the big ones) check dc offset sa speaker terminal.

psu section sis, asan? history, bakit nagkaganito? (kung nagkuwento owner)

 replace main filter ecap of higher capacitance value and voltage rating.

if shorted output trannie, diba naopen yung emmiter resistor niya sis? 0.22ohms na 2watts?

try mo na walang pre-amp, check mo din voltages PSU mo
with great power comes great electricity bill

check mo na rin ang mga transistor na paisa isa yung 2N5551 at 2N5401 at yung resistor dapat eksaktong 100ohms din ang ikabit.check mo na rin ang mga 2w/0.22ohms resistor tulad ng nasabi sa itaas at sa pag test pwede naman wala muna ang output transistor para ma test muna kong may dc offset sa output ng amp.

Palitan mo lang mga sira, at check kung di shorted ang speaker.
2 diodes ang biasing sa LTP CCS tranny.
Series resistor + diode sa biasing ng driver trannies.
Sunog ang mga driver trannies at output pati resistor ng driver, maaring open ang mga 0.22ohm resistor.

^advice ko lang yun at para iwas din backjob. yan ang ginagawa ko sa mga china speaker amp na dumadating sa akin. kasi based on my experienced palaging bloated dahil underrated siya. then maliit din capacitance value.
