CTC-7 no high voltage

[Kamakiri]

I never had the "stones" to play that arc-to-screwdriver game.

I have a neon bulb attached taped to the end of an empty Bic pen body. I hold it close to key components. If the bulb lights, there's HV.

Much safer IMO.

Are you sure you plugged the yoke in? There's a jumper that kills HV if the yoke is unplugged. Also the vertical section will continue to run with the yoke disconnected, which makes it very hot with no load. You should pull the vertical output tube if running sans yoke. Have you recapped the horizontal board yet? If not, you probably lost H-drive and the h-out tube is probably overheating. Look for the plate of the H-out tube to glow red in a low light situation, that will be a dead giveaway that you lost your horizontal wave form.

From what I think I am seeing I don't think the Horiz output tube is even glowing.
