After acquiring some more 6SN7s and eliminating the vibration-sensitive one, the funny business is back. I swapped out the horizontal oscillator for the four ones I have now, and I'm still seeing funny business like weak HV, blooming, etc... and I doubt that all of my 6SN7s are that bad. I'm left scratching my head because the symptoms aren't consistent with changes I make - e.g. swap the damper, picture is suddenly dim and blooms. Swap it back, it doesn't go back to the way it was before.
Having had suspect HOTs and dampers already, I need to pick some expert brains... What kind of symptoms can one expect for weak:
-> H. Oscillator
-> Damper
-> H. Output
Specifically, are there differences that can help me ID the culprit(s) without a tester, or are those symptoms all over the place?
