This is something I'm not understanding: I have the radio back together. With everything placed as it should be, I hear a small whistle. When I remove the cap from the interstage coil to the input grid (top cap) of the 36, I hear stations!! Garbled, yes, without any RF amplification. Put the cap back on and there's the whistle. With said cap off, I close-couple my hand near either the top cap or the connection and my reception picks up. So the O-coil is working. But what is going on??
