thanks... update this thread soon pag andyan na pyesa wag lang mapeke sa IC ;D

J@M pwede ko kaya palitan ang IC nito originally STK402-100S @100W to STK402-120S@120W kakayanin kaya ng default power supply?

ok lang yung stk402-100 papalitan ng stk402-120,check u muna dalawang 100 ohms 1/2 watts na resistor,papuntang paa ng ic,if ok...pwd mo naman tanggalin yung mga paa ng ic...para ma isolate mo lang problema...pagtanggal ng ic at magnormal power,8s means ic talaga problem nya...

tama si sis samiel, check muna dalawang 100 ohms resistor na connected sa dalawang main filter caps , kakagawa ko lng ng compo kanina, 2resistor lang sira.hihi sirain tlga yan, check u muna po bago pagsuspetsahan ang power amp. Check for loscon din lalo na sa mga connectors,hihi .. Gudluck po sis! Mabohay
