It should generally be around 700-900v with the controls at maximum.
I wasn't able to get a setup line on my CTC40, and it turned out to be a bad HV diode in the circuit that supplies the G2. In my case, it also caused the focus range to be off.

During testing, the range for each G2 control was roughly 450 to 729. The reading was taken directly from the output tap on the G2 pot.
