[R-390] R-390 POWER SUPPLY

[Dan Merz]

Clarence, hi.  Is this sound coming thru the speaker or is it a vibration
coming directly from the supply transformer and apparent with the volume
turned completely down?  From your description, "not ac sound",  I take that
to mean that it's not  ac line hum coming out the speaker,  which is
generally fixable by capacitor replacement.  Are you blowing fuses?  Dan.
