[R-390] EAC power hum

My 63 Imperial had hum coming from the power transformer. It was vibrating the PTO slug causing a low hum on received signals. The fix was to very loosely mount the power supply.  I don't know this for a fact, but there is probably a chassis ground wire within the power supply cable. This same transformer also had the tar potting short out at the high tension winding ceramic feed-thru bushings.
