My antenna was giving me a ground loop. Those caps are OK.
Riders says that the P-K voltage on the RF tube should be around 165 volts. I can see this in the 112 schematic since it has several resistors in the B+ but not on the 15. It is about 290V. Resistor 10 (160K) is right on as is cap 5 (.05uf).
The reason that I was looking at the RF amp is because cap 5 (the other half of a dual .05uf Bakelite block) is taking most of my signal to ground. Everything is fine with it out of the circuit, both in the local and distance settings.
