Thank you Mondial.
I have a quick question regarding the oscillator coil on the 19B. Hopefully someone knows this. In my set, the coil that is open is the small coil connected to the cathode of the 36 tube. All of the other coils ohmed out ok except that one. I removed the osc coil, but I am uncertain about which set of turns is the one I need to replace. Here is a picture of the coil,

I believe it is the light-shaded one nearest the terminal lugs on the right side. This would be the bottom of the coil when the radio is right side up. Is this correct? The coil that is open connects to terminal lugs 1 and 2 if you start at the clamp that holds the osc coil in place and go clockwise.
In addition, I wanted to share the technique I used to count the number of turns on that coil. I had tried to do it by rubbing a pin across the turns, and by looking through a magnifying glass. This is probably an indication that I had too much caffeine today and I'm going blind, but I couldn't reliably count those turns. So I took a close-up picture, then displayed on my largest monitor and zoomed in as close as I could. Looking at the zoomed-in photo made it pretty easy. I counted it four times and each time the count was the same (27 turns if anyone is collecting this info for future reference).
Thanks,
Jon
