Thanks TA. The radio did this when I first got it. I will recheck my work but did check after the big can. About the same. After the bakelite blocks, about the same and after completing the resistor change out, about the same. It really is not a high pitched screaming sound, more like a rapid lightning storm of various intensities. Seems worse at high volume, at low volume I can't even see it on the scope. Short the grid to the RF amp, still there. Short the grid to the first detector, it's gone. Something is going a little wacky in between the two tubes. Of course the oscillator is in there as well. There is a couple of mica caps in the area that I have not changed. If that helps any perhaps you have some ideas.
Appreciate your time. Also, anyone who can answer my previous questions on labels for the shield would be great.
