If it's a CTC-12 clone then you will not have the same problem with the blanker tube bias effecting the HV production, that did not happen until the CTC-15. It was a backup to runaway HV if the shunt tube failed.

If it has a 1.5 meg resistor from the control grid of the HOT to the term TT on the chroma board, then you have the blanker tube bias issue.
