Yes it's tough to measure on the CRT connector, which is why I suggested to find the end of R44 which is under the chassis and connected to a wire going up to the CRT socket.

I was referring to which set of terminals is for the brightness control, because the brightness and contrast pot is double-ganged pot an inner pot and an outer pot, and both have three terminals.

Although it makes no difference as I got the measurements I needed, and everything is measuring as it should except for pin 10 of the CRT Socket which is measuring at 404 VDC rather than 380 VDC, but Pin 11 of the CRT Socket (the center tap of the brightness control) is measuring between 15VDC and 140VDC like you said it should when the knob was rotated.

So the 404 VDC on pin 10 of the CRT Socket, does that mean something is wrong with that part of the circuit, or is that just because of the higher line voltages?

I think it's close enough. See my previous post about measuring voltage on pin 2 on the CRT socket. If these 3 voltages are in the ball park you should be good to see if you can get a raster by adjusting the ion trap.
