After another search I managed to find the schematics and such for the tester. It gave me the wiring diagram for the cable that connects to the various sockets. From there I was able to match up the socket to the cable and found that one of the wires is oddly out of place (or at least it is to my thinking).

I am attaching the pinout and voltages of the CRT and am hoping someone will tell me which voltage is which on pins 5 and 2. I know one is G1, but is that the negative voltage or the positive? On the socket, the G1 (-53.3V)is connected to the CRT on pin 5 and the K (53.7V) is connected to pin 2 of the CRT. If those are correct, then the only issue is the socket has the G2 (RED) connected to the G2 (GREEN) of the cable. It should be on the G2 RED as that's the adjustment for monochrome/BW tubes.

So I need to pull the pin out of the connector and move it from 10 to 9 so red G2 is connected to the CRT.
