Ok guys, I have an update.

Last night I checked the resistances of every winding on the flyback except the HV winding. Every winding was in spec. The flyback is good. I then went over my recapping and saw that I made a mistake. I connected one of the caps to the wrong terminal on ther tube socket. After fixing that, I checked B+ voltage on the H output tube. It was 30 or 40V below what it should be. I then suspected the 680k plate resistor so I measured it and it read 2.1M! It drifted quite a bit. I never got any farther because I had to leave for work. I'm going to replace it when I get home and check more plate resistors. I checked the voltage on the top electrode of the horizontal output tube in respect to chassis ground and my volt meter measured a little more than 400V as it warmed up. After it warmed up, my meter would beep and go nuts, even though it's set to 1000VDC/750VAC. Silly me, thinking that the resistors would be fine.

I suppose the best thing to do is check all the resistors and replace all that are more than 20% out of spec?

Thanks.

Jonathan
