On most of the Fender blackface and brownface amps, the bias supply is tucked away on a little board in the corner of the chassis. What's the advantage to having these components (diode, cap, resistor) physically separated from the rest of the circuit? Noise suppression, or were they just trying to pack stuff into unused space?
It seems you could just make the main circuit board a little longer and stick these components on the end. In fact, that's what Fender did on some of their earlier amps with the selenium rectifier (5F8 Twin for example). So, did they find that the bias supply introduced noise into the circuit and moved it away?
