Well I believe Im on the right trail diagnosing this problem. I have my nib sylvania 3a3c, a thordson nib horiz eff coil, and my hex tool. I was looking at the schematic thinking why after it warms up the cathode current becomes excessive. So I thought I should make sure everything between the horz oscillator and output tube is in order. I found a .01 cap going to the grid of the horz op tube. Said cap had broken solders. So Ive stuck a new .01 in place. Also I plucked the damper tube and noticed little cruddies shaking around in it. My precision 10-12 cant test compactrons without an adapter but I dont think little bits of crap jingling around in a tube is a good qaulity. I dont have another tube so I have not fired it up again to see if thats made a difference.
