Bz-z-z-t. I shorted the pilot light. That killed the bulb and also blew the fuse in the variac. I'll drop the question about resistance/continuity for now and probably discuss it with my brother, K3KU.

I put everything back together, powered it up to ~115V, and it works well. Good local reception with no antenna.

Question on hum: For the electrolytics I've replaced 30-25-20 with 33-22-22. Can I increase the capacitances to reduce the hum?

Thanks to all. I know it's nothing to write home about, but I'll post something when it's done.
