Re: HV PSU Question
Have you tried it with a lamp limiter in the primary circuit? With no load on the secondaries, the current should be low enough not to cause (say) a 60W bulb to glow (or if it does glow, only a very dull red on the fillament wires). If there's a shorted turn somewhere (and it could be in any of the windings) then the lamp limiter will light up.
