Thanks Tom.

That's the one pot assembly I haven't cleaned yet. I did find tin whiskers in the other two, but I didn't see anything from the outside on that one, so I let it be.

Edit: I did clean this assembly, but no improvement. I didn't spot any whiskers in it, either...

Did you have the negative voltage readings on the 1st IF input and AGC plate as well?
