Conventional BJT amp in mono configuration. I'm converting them to stereo units and the first one, where I reused the internal wiring from the other, works fine. I had to rewire this one using a foil shielded two conductor (15awg) wire, shown here: AUVIO 25-Ft. Roll of 15AWG Round Speaker Wire : Speaker Wires | RadioShack.com. The original wiring in these units uses a two conductor cable with braided shield with the shield tied to ground on the source (rca) end only.
Amp is buzzing from both channels and goes away completely when I insert shorted plugs in both rcas. If one at a time, the shorted channel goes dead quiet, other continues to buzz.
Is it the unshielded wiring that is causing this buzzing? Any suggestions for further evaluation of the source of buzzing?
