Hi, is it worth fixing? An otherwise functional 3000-2 beomaster had an intermittent channel, regardless of output source. Pressing on the elevated, smaller circuit board with all the orange caps on it allowed the missing channel to work. Thinking this was possibly a bad ground I attached a jumper wire from the ground terminal (which had a ground wire leading to earth). the other end of my jumper touched a tracer , seen in the first picture. Arrow points to a small black spot where a spark flashed. That totally eliminated the intermittent channel. I pushed the balance slide to the other channel all the way, and was listening to the radio for about ten minutes, when a pop, flash, and smoke came out of the metal box shown in the second picture.
Is it likely that numerous components got fried, or perhaps only a couple that would be observable, and replaceable? Is it worth a couple hundred dollars to diagnose and fix? Thanks
3000-2 is a nice amplifier and it will be repairable depending on your skill set.
I would suggest it would need restoration now either way due to the age. That said, they are pretty common, not exactly valuable and so you may be better finding another unit.
