think the answer to using it as a power supply is to turn it into a
VOLTAGE regulated power supply by taking a voltage sample off of the
HV transformer, possible by adding a couple of turns coil to the
transformer, and replacing the input from the current transformer with
this one. Naturally the inpit to IINDO may have to be suitably
modified also.
==========================================
You might consider taking a voltage sample by 'tapping' a low DC voltage
fraction from the HV output ,putting that into an opamp with adjustable
output.

You can see how this is done in an article in QEX-July.August 1999
,pages 50-55. 'A regulated 2400 V power supply ' by VE6AXW
