2. HVPS Rework

I thought I would start off by replacing bad parts on the outside of the potting. I will start off with the G2 control circuits. The resistors in mine were way off and they are carbon type (the worst kind of resistor) they get out of spec if they get hot and they also add white noise. I think this might be what causes some of the faint snow that has been seen in the background by some people

Start by removing the bad resistors - you can see I have removed one already:

All 6 replaced:

Note the air gap don't let the resistors touch the PCB. They need air flow for cooling:
