Roy (from Roy),

This is a wild guess:
There is a modification to add a capacitor across the plate overcurrent relay in order to prevent dropout of the high voltage on voice peaks. It's conceivable that the mod was done with the wrong value of capacitance. The cap is mounted below the relay under the chassis.

Others may well have more relevant experience. I look forward to a better answer.
