Hi
This time can somebody help me to find the schematic for a fisher sa-400 amp.
I have some problems to bias this amp because I think that one of the previous
owner modify it to be self bias and I want to rebuilt
it to original. I think he change the resistance between
the cathode and the groud (actualy 50 Ohms) and put a capacitor
of 150 uf between cathode and ground. So can somebody help me.

Hi,
Try here:

You should be able to get a better idea if your values are close to right based on other makes of units. I know one of the guitar amp sites had some Fisher schematics but which one I forget. There should be Photofact available if nothing else.
