I wonder if the power transformer was changed because I own five 500c and one 800c receiver and not one is riveted together nor are the many I rebuilt.
Just disconnect the two power supply diodes in the doubler..You only have to lift one end of each. If the buzzing goes away,I have seen shorted or leaky filter caps in the chain cause loud transformer transformer oscillation on occasion.
