Ok, so here is the loaded question.
If everything else checks out and tube swapping, caps/resistor checking, etc. fail to change the condition and we are looking at a possible sawtooth waveform issue - where do I go from there? That waveform comes from vertical osc tube, correct? So either the voltages are fine on that tube and the issue is with the tube itself, or the voltages are off and I have to track down where the problem lies feeding that tube, right? So test voltages back from tube to tube in vertical before osc tube until I get to a point where they are correct. Then my issue lies between osc and where they test fine.
This is all assuming that controls/caps/resistors, etc are all done and good. Just wanting to make sure I have the concept down really for diagnosing.
