[QUOTE="1200GXman, post: 1123474, member: 17884"] Well, I picked it up and it worked fine upon testing at the seller. Now I possibly have an issue which I don't know why it happened. I plugged in a set of earphones to test it. I used my cellphone as music input and plugged it into the Aux in. Luckily I had the top cover removed to see if there is smoke(which happened) or excessive heat. Switched on and couple of seconds into listening smoke started to appear. I immediately switched off. It is a resistor that burned which is attached to ground in the right top corner if looking from the top. Easy fix but my concern is why. The amp looks completely original inside. Nothing has been replaced or modified. Only the speaker terminals have been replaced and they look fine and the amp was working fine on speakers at the sellers house. Will get service manual online [/QUOTE]
