Thanks fellows for the on target comments re: the errant Henry 3KA.
Removed the OEM HV 10Hy choke and temporarily installed an 8Hy
swinging choke I had lying around. That did the trick. Voltage was back
in the safe area and all's well that ends well. Appreciate your input!
Now the dilemma! Should I attempt to locate a difficult to replace 10Hy
choke (.8amp) or simply replace the entire supply with a small
footprint, appropriately sized Hipersil w/capacitor input circuitry and
perhaps shed 200lbs of iron? The power supplies I design have filter
caps, bleeders, and full wave bridge circuitry on a 6x9" PC board and
are rated at 6KV@ 2+ amps. The plan for this rig was to install a pair
of 8877's once I complete the 2K4/8877 currently on the bench.
