There are some paper caps left but I think only in the audio circuit. I haven't hooked up the scope yet but today I dug out my Sencore sweep circuit troubleshooter. HO tube cathode current looked normal & adding drive from the troubleshooter had no effect, though I did notice the damper wasn't glowing like before. Using the troubleshooter's yoke substitution test didn't help; when using its flyback test it points to either a bad fly or something in the load circuit, according to the instructions. Further clues: when I started, the fuse in the yoke circuit was blown. Also, I have replaced the damper, rectifier & HO tube with NOS. Outwardly the fly looks normal. I have also tried hooking it up to my Sel-Son crt subber, which I figured would eliminate the yoke from suspicion. No variance.
