Thanks Ron! I couldn't find it anywhere.

I have experienced the same thing as Steve. I have done three of these now. Generally, I managed to get them to work with the 36 tube, but it is a real crapshoot. You can do all the steps, and it still maybe not work completely. The whole thing is real unpredictable.

Recently I posted that I made the switch to the 77 tube, and that did work well. I have another 89 sitting here to restore. If I have trouble with that one, I may go right to the 6A7 conversion.

I have couple spare coil forms so I would not have to destroy the original from the radio.
