Bascially. Any that I didn't change were tested. All paper capacitors were replaced. I didn't change any ugly looking ceramics based on feedback from the forum and the fact that a sample of them that I did test, tested good.

The radio section is comletely independant except for the 6AU6 1st AF and 6Y6 power amp which is shared by the TV. The problem only occurs with the FM. The TV and AM audio are fine.

There was only one electrolytic in the radio section and I changed that in the beginning since it was shorted. I changed the two micamolds that were in the radio. There are other micas that aren't micamolds. I'm hoping it's not one of these micas because I'd have to remove most of the other components just to get at them.

Also, I've checked the HV to the radio and it doesn't change. There should be 215V on the plates but it's 238V. I've tried lowering it by running the set on a lower voltage with a variac, but this doesn't change the fading.
