This indeed looks like an interesting project. I wonder how a 405 line television ending up on this side of the Atlantic? I suspect the unwitting owner when emigrating to the US years ago did not know about TV standards.

It will be fun building a modulator as it is positive rather than negative modulation with AM sound.

And with the converters made with FPGAs, I wonder if anyone had ever considered or produced a convertor for 525 59.94 to 405 50Hz ?

As for the CRT, it looks like the 17BP4 can be made to fit.

I also noticed it has a spot wobble switch on the back! Never knew that spot wobble was ever applied to consumer receivers.
