I've got a model 65 receiving and playing wonderfully. I'd like to reduce the 60 cycle hum which seems to be a little louder than it should. It does not increase with the volume control. It's constant and at the same level as long as the set is turned on. The set has a x2 safety cap across the ac supply to reduce line noise from the house. It seems like this hum is coming from the transformer. Any ideas?

Thanks, Dave
