Even with as out of spec as the PSU is I have been getting intermittent traces on the screen and one of the two traces was pretty clean. The last time I turned it on I heard a pop and shut it off quickly. When I turned it back on the traces had returned but things were different. There was a significant amount of noise/distortion on both traces. Trace 1 was blurry but not as blurry as before and trace 2 now shows equal blur. Then the traces faded again. I could not locate and visibly damage components on the external boards. Prior to this I did swap out the .0047 6kv paper cap with one from a 468B because I thought it was reading bad out of circuit. Im not sure if its related since newer part was identical.
I am going to get a second 465B that I can use to compare readings on components with to help me isolate the issues. This way I dont have to pull parts off of boards to test as much.
It seems there are at least two faults I need to deal with. And eventually I believe I will have to recap the PSU and maybe more.
