"further down and a bit to the right, just under where the power cord emerges from the panel, the photos I’ve looked at say something like "for continued fire protection use original fuse type and rating only of MDA-10."Al, I appreciate your research into the correct type of fuse. I didn't see the instruction on the back of the amp since I have a conduit on that shelf to separate cables.
My first move will be to pick up some Bussman MDA-10 fuses and return the amp to baseline. Thanks again for the info.
BTW, all contacts on my amp were cleaned not very long ago, and I will clean the fuse holder.
