Since I could not find a reliable way to determine the outside foil of the caps I decided to swap the caps around one at a time. There was no change at all. What I have noticed now is when I take the radio upstairs I get a few more stations and they don't have the squeal. It is just one spot on the dial with the squeal. So I'm thinking it is something in the house interacting with that station. If you guys agree I am going to call this one done.

I did not like the 13 volts showing on the first 12BA6 so I removed the CL90 and replaced it with a 120 ohm 5 watt resistor. All the 12 volt tubes now run about 11.6 volts.
