Hi, my dad just got me this amp from e-bay the auction said no output, since I have experience with building amplifiers I decided to buy it and fix it, because of the low price. Well I connected it, started playing got excited for a minute and then I heard a "thump" from the speaker and the offset LED came on. I tried it again and same thing after a few seconds of playing music. So I opened it up and one of the transistor was getting extremely hot, but when it is cold the amp works just fine. The transistor is in the poweramp section of the PCB, has nothing to do with the output MOSFETs, if anyone has a service manual for this please let me know, greatly appreciated.

Regards,

Petar
