That thing must do a little re-biasing of the G1, a little more positive and possibly even boost the heater voltage a little.... Simple resistor network off one of the more positive going pins, couple meg-ohm resistors, a slider pot, and there ya go.... Accomplishes the same as a brightener and resetting the screen bias, but sold to home owners for a profit, so no real need to learn them anything about those 50 little turnie things back there. Almost like the thigh-blaster from the 80's that also came with a fitness and diet guide..... Guess what actually got the weight loss done.....
