Not surprising, given the application. I'd appreciate substitutes.

The Tek number is 152-0398-00, that might cross to a 1n4935. Mouser
stocks those at $0.06 each, quantity 1.

I agree. I only have the 2440 schematic in front of me but based on
it, those diodes need to be fast recovery rectifiers or better. Most
1N400x series will fail in that application and they certainly are not
specified for it.
I may take a closer look for suitable substitutes later.

I don't think regular 4007s will survive, I think you need UF4007 or similar fast recovery diodes.

so I put in a couple of 1n4007.
I think one of the diodes shorted again.
