nothing definitive, the horz osc plate load resistor had drifted up some to 92k shb 82k not much but then again, maybe just a tad less drive. While I was in there I went ahead and replaced the .01 coupling cap, it was a small brown drop rated at 400v, it sees a pretty good sized pulse so I put in a .01 1kv dipped. those boost caps are all disc, I really doubt they are leaky, and they had the spark gap cardboard spacer on the lead that I did not want too fuss with.

the diode used in the bias circuit of the HO tube tested fine, and the resistors that form a voltage divider (1.5 meg and 12 meg) were right on the money. There is a small 680 pf disc cap that supplies them from the flyback, it looked fine I just can see it being bad, will leave it for now.

did switch to the HV tap, so before doing anything else will see what it looks like now (couple cap,plate load resistor, and PWR Xformer tap).

I still don't like the looks of the eff coil slug being up so high, but I dont like to make too many changes at once without testing.

Oh forgot the 18k I will have to get one of those from the surplus store tomorrow, I want to to that before testing again as the service man said that should always be replaced.
