Hey Ron,
Question about the "gimmick" capacitor.
I finished work on a Model 19 cathedral a little while back. I had rewound the tickler coil a number of times trying to get even minimal performance out of that 36 oscillator. My last and most recent rewind seemed to work the best, though that is to say, barely at all. I had done the coil baking and from what I could tell, I followed all the advice available.
However, when I soldered a 2 foot piece of hookup with to the cathode of the 36 tube and just let it poke out the back, the radio comes to life and works beautifully across the entire BC band. I tried various mica capacitors to replace the capacitance I supposedly introduced by the wire (gimmick capacitor?), but no luck.
My next step would have been to do the 6A7 mod, and I still may do that. However, I was suffering from "Model 19-fatigue", so I left the radio as-is for now.
Why have you never recommended the 36 cathode-gimmick capacitor for the Model 19 like you did for the 80 and 84 models?
BTW...I really appreciate all your great advice as well as that of so many other members on Philco Phorum.
