I am still digging into this HV unit which is giving me some troubles. Here is what I have observed. The collector of q901 is way off of spec and I don’t understand the circuit well enough to understand what is causing it. And the base / emitter of Q900 are about double what they should be. I have checked the values of all the resistors and they are fine. I have replaced q900 with a bu406d (verified good in another HV unit).I have replaced q901 & q902. Any suggestions? Thanks. I have attached a copy of the schematic with my noted values in red.
