Ah! Thanks, Ron. Didn't realize that about the 6J5 tube. Will check pin 5 of the 6A8 and the cathodes tomorrow.

This one is being especially stubborn in coming back from the dead. I'm not getting any response from the antenna (RED terminal) when I connect a long wire antenna to it (or even just touch it with my finger). Yet the antenna coil (and all other coils) ohm out to the values on the schematic.

The set howls and whistles, and at full volume it motorboats. I can only get the strong local station (somewhat) if I clip the antenna right to the tuning cap. I'm not sure the volume control is the original. It looks like it's been in there forever, but the shaft has a very narrow stem. So much so that I large shim is necessary to keep the knob on it. Wondering if that volume pot could be a contributing factor?
