So here's where we're at.....something peculiar.
Vertical output transformer ohmed out fine as it turns out, I could have sworn that would have been the issue.
Now....
HV is great, but no vertical sweep, and hotizontal sweep is ONLY evident on channels that have a signal. If there's no signal, the screen goes dark. We checked and replaced a couple resistors in the vertical oscillator circuit that had drifted high, but nothing that was either shorted or open.
