I've looked, but the SM doesn't note which is which. I determined the G2s are white with 540 to 640V, so those I don't want. The other two sets are the video outputs and are yellow and have 142V and the last set are R, G and B and have voltages of 36.4V. I'm assuming the video outputs of 142V are G1? Those are also where the chroma gain taps are.
So if the yellow leads from the video outputs are the G1s, then they have test points that I should be able to connect the gun killer clips to. Those test points are where the G1 wires go to the CRT.
