need help fischer rs-2015

[jeremiah7734]

I have a fischer rs-2015 and I have distortion out of 1 chanel and the other cchanel nothing I found a r13 resistor burnt and a fuseable resistor popped I replaced them and still no sound

The resistors burnt and popped are a symptom of a larger problem. If you can compare the transistor voltages on the boards with actual meter readings, that might nail it down to a few parts. I would do testing of the output's on that side 1st, per this thread (you can do this with all transistors)...

thank you that's helping alot

Hi Jeremiah, did you figure your issue out? I have a similar one, my right channel is kaput. I was able to determine that one of my transistors was blown, and I replaced it, but the resistance is still reading lower than the working side. I think there's something blown on that side's amp circuit board - were you able to locate a schematic, by any chance?
