Jeff, G2 goes from pin 8 of flyback to pin 1 of J9 which should be front right
of fly then goes
to P/J26 pin 5 through R19 a 2.7K 1/2 watt resistor on the crt board and then
to pin 7 of the crt board.
Schematic says at pin 8 of fly 350V minimum to 900V maximum. The 215v on pin 2
of the
plug your measuring is B+ from flyback pin 9 which is for B+ to the RGB
transistors on the crt board. To
better understand, here are the 2 plugs voltages;
J9 pin1=G2 pin2=200v pin3 No Connection Pin4&5= Filament
J/P26 pin 1&2= Filament pin3= No Connection pin4=200v pin5=G2
I Hope this helps you out, Let me know if you need more, Larry E
