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.

Next I replace the input filter caps. The new caps are smaller so I scraped the solder mask off the trace and just soldered one pin of the cap to the trace.
Notice the burnt white cap..

Now the next 2 caps and resistors and yes those little guys are 2 watt I rechecked when I got them and I even ran 20Volts through them just to test that they are 2 watts

Notice the air gaps on the resistors the leads help cool them and I have the caps as far as I can get.
