[R-390] Need help fixing R390A not to trip GFI breaker

[Jim Pruitt]

I am looking for some suggestions in repairing my R390A so that it does not
trip the GRI breaker (outlet) here in the garage/radio room.  I thought I
had a power supply problem until I tried the radio in a non GFI outlet and
it worked ok.

Thank you.
