Philco 40-201 Restoration Journal
#13

Thanks for the encouragement. The thing that really caught my attention is the fact that everything flows through that coil and mica cap right out of the RF tube. It looks like a low pass filter but I'm sure how the configuration with the coil in there affects that. Time to do more reading and not be hasty with the solder iron. I've got a signal generator and a scope that I need to put to good use. For now I'm going to assume that all of my coils are OK. I don't know what to do about checking the caps that are tied up with them. Until I find some really good evidence to crack into the coils. I'm staying clear of them.

Tubes: I couldn't find anyone local and I had one glowing purple just after my recap so I got replacement that were tested. Only my 42s on the output are not new/tested so I'm not too worried about the tubes being the problem. Loctals are an annoyance but at least they will stay seated in an earthquake.
