fortunately for me, I had two working ones.
Dennis,
Could you use a pair of 7A22 Differential amps instead of the 7A13? Or a single 7A13 for X and single 7A22 for Y?
I know for sure that I have a pair of working 7A22s or at least one 7A13 and one 7A22 working.
I am interested to see how this works, don't really have a 576 or 577 with a "bad" CRT, but it would be nice to kow how to make this work just the same.
Thanks!
