Hello, Hoping that you can help me with a couple of questions regarding the 37-650. There is a resistor soldered between the Pin 5's (Grid 1) of both 6F6's. It has an Orange body with a Yellow stripe and measures about 400Kohms. It doesn't show on the schematic! Can anyone confirm the appropriate value of this resistor? Second, there is a Bakelite cap (8035-DG), containing two 110pf caps in the 2nd Detector/AVG (6J5) circuit. Philco rated them at 1000V. I don't see how there can be more than 300V in this circuit, but I could be wrong. Can I use 500V rated caps here? I appreciate your assistance on this. Thanks,
Joe
