wad 300b pse monoblocks feedback problem
Just finished building 300b monoblocks, all is fine when FB not connected, but when FB connected the bias voltages are all over the place.(see attached )
Have checked wiring numerous times and all seems fine, both amps have the same issue so it must be something i've done but i just cant figure it out.
The rectifier is a 5AR4 so the voltages are a little higher than design
