My big Kutztown purchase was a Crosley 307TA, basically an early 630 in a slightly different cabinet, with different knobs and trim. I tried to wake up the 10BP4, but it is reading dead on my Sencore CR31, although the filament lights. If resoldering the pins doesn't help, I will try to reweld the cathode; beyond that, I will be looking for a replacement.

The CRT could be asleep (if not used regularly the cathode acts as a getter and develops an insulative layer of crap over its emissive surface over the course of a few months/years/decades). Leave it in emission test mode for an hour, and if it does not register anything up the heater voltage to 1.4X it's designed value, switch to emission mode and let it sit for 1-5 hours (once emission hits the good range you can stop cooking the heather).

Yeah, love to see it! The Crosley version of the 630 is quiet nice.

I once had an RCA 641 and when I looked in the back I found the chassis was a Crosley, swapped in long ago.

I made a swap with 630TS years ago for a Crosley chassis. The original was a mouse nest and a friend so happened to have a completely recapped Crosley chassis. It just drops right in.
