Hmm! Since the radio is on my bench still, I turn it on for a bit of a play whenever I'm in the garage. Today I turned on, and a second or two later I heard "POP!" and saw a spark between the first IF can and the chassis.
Aha!, here might lie the source of the odd instability I have occasionally run into, where it sounds like the IF is oscillating/regenerating. More later.
Oh, and I tested the temporary antenna I had been using on a modern Grundig portable. No wonder I was confused. It made signals worse, just as it had with the 1938 radio.
Cheers,
Ed

I don't hold with furniture that talks.
