CRT Universal chassis Question

[Stickman]

So I have a tube which is a high impedance Hitachi, and I have a high impedance universal Wei-Ya chassis.

I now realise I cannot count as the tube has 12 pins and the neck board has 12, but two are blanked so only accepts 10 pins.

Is there anything I can do other than alternative tube or chassis? I cannot find anything online about the tube and pin outs so looking for some expert guidance.

Neck not compatible with socket. It's a neck used in pretty old Japanese monitors.

Whether the "high impedance universal chassis" is electrically compatible with the yoke of that tube remains to be seen.
