I rechecked the tube and Pins are correct as labeled. Pin 7 has 270+ volts
on it.
That looks like G1.
I have never in my life seen such a high G1 voltage. It is most
certainly G2. In that case the voltage is a bit low, which is either
caused by the load of the voltmeter, or somehow related to your problem.
Sorry, I goofed badly. G1 is probably earthed on the CRT PCB, probably
via pin 5 or 12? Otherwise G1 grids are most often driven negative,
IME.
There are 2 pins in the 'key' that have wires running back to the
flyback.
Probably Focus and G2/Screen.
Wrong again, probably. These are the 2 focus connections.
Yeah, I missed that.
