Okay!

I put everything (upper and lower chassis, woofer, tweeters) back on the bench this evening and tried it out. Plugged it into my Variac and set it to 110 V.

After running for about half an hour, the 3K resistor is hot, but I can keep my fingers on the chassis where it is mounted, so it isn't hot enough to burn.

The 2.2K resistor is lukewarm.

The power transformers are fine, barely warm (if that).

Moral of this story: The 37-690, like any vintage radio, prefers 110 V to today's 125+ V line voltage. So this one, I believe, is good to go and ready to launch. Icon_thumbup
