Screaming Picture Tube???

I'll have to look into this more. When I was working on my Hoffman TV I accidentally touched the anode with my left hand, and the chassis right my right. I heard a psst and felt a shock across my neck and arms! Well I don't want that to happen again! I'll have to bypass the interlock somehow in order to check for a bad CRT. Like you said, KHTV, hopefully not, or I will have to just sell it for parts. Of course, once I get it wired that way, I'll have to check for the other noted situations as well, like the yoke and flyback. But hopefully it's as simple as the anode cap.

I brought in a large video monitor today that has a similar problem. However the CRT seems to work normal, although the input VHF signal is not getting through. Perhaps this problem or more complex. With the Zenith, hopefully it's just some bad condensers or resistors.
