Recap 48-482

I've found something interesting as I was cleaning the tube contacts...the 5Y3GT rectifier tube has been replaced with a 5U4GA/5U4GB. Is that a compatable replacement? Maybe I'm grasping at straws, but I really don't want to have to recap the radio.

Update: while cleaning the tube contacts, I also cleaned the pots and selector switches again. As I was test driving it, I noticed that the treble pot seemed to be the offending component. All of the voltages are still out of spec, but the radio is playing quite nicely, and has now for several hours.
