Audio Hum

[Mikegjax]

I am getting a fairly loud audio hum over the speakers when the Magnadyne is on. First thought it was an air-conditioning rumble but now know it comes from the radio. Does not matter what audio source is selected. Anyone other than myself experience this and if so, what was the cause?

Issue was disgussed before and here is the link. Parts cost me about $45 bucks. Thanks to jim's discussion w/ an FR' s, EE my hum was reduced considerably.

Most likely the radio itself allowing higher value current to run over the output speaker current. You need a radio am to check and fix it.
