> Yes, these are the postings that never end. I am getting so disgusted with this G05-805. I was able to get a working HV diode and the problem of shaking and blooming still shows up. When powered up totally cold, the HV is fine, maybe even a little over. The image on the monitor,however, has a very small case of the shakes and as it warms up the HV (about 5 minutes or less), the image starts to expand and the HV starts to drop. It was down to 10.8 KV when I got disgusted, cut the power and left.

I am about to start at square one and start measuring, rechecking and reverifing things I am taking for granted is working. I am so tired of working on this problem and it's starting to get in the way of other projects.

The high voltages I have done, but what other voltages do I need to check? I'm starting over so what other "DUH" type things do I need to check again? Oh, and I am afraid that I don't have an O-scope, so I tests will have to be adjusted accordingly.

maybe the big cap on the power-supply tray in the base of the cab?
