So the HV board that is in the scope now is not the original but rather a "new" board from QService. I had hoped this would be a known good board. Perhaps that is not the case. The original board had a cracked HV transformer. Do you feel strongly that I should start replacing resistors on this "new" board?
I have the luxury of being able to compare resistance values across both of the HV boards that I have albeit this testing is in-circuit and with one of the boards installed into the scope (connected to power supplies, etc.). My measurements are similar between the 2 boards.
My A1 board does have the carbons for R710 and R910. Both test about 2.3k in-circuit. Do you have a 2465A and could test some of the resistances across these resistors? Don't get me wrong. I can start swapping out resistors but would hope there is a decent likelihood of that solving the problem.
This is not what is seen with an IC failure right?
Any point to checking more voltages at the CRT socket?
