New to the forum so Hello's and Howdy's all around. The issue is with boards I built and installed on a PAS preamp.
I hooked up a Leader signal generator and input a 1kc square wave to the magnetic phono input.
What I saw on the scope was anything but square, more like razor wire.
Thinking that maybe an error on the board I placed an original Dynaco PC-6 board in.
Same result.
After some investigating, if all the caps in the feedback stage are removed, back to square wave.
The question: Is this correct?
Thank You
