I have not done any convergence yet but here is a picture of the VA62 multiburst video response test pattern. And lastly a black and white picture of some video. Color does not yet work, and IIRC, that was the main problem I had intermitantly 30yrs ago.
I checked and found the 3.58MHz oscillator is not working. I tried the one other crystal I have and that made no difference. I guess I will start changing what parts I can in that circuit. Is it right that I can disconnect the reactance tube plate coupling capacitor (just to isolate and simplify the circuit) while I get the oscillator working?
