Risking ridicule, a suggestion.

Put a silicon diode 1N4007 in series with a resistor, say 2K @10w across each anode to the cathode of the GZ34 to advance the HT voltage rise before the GZ34 conducts the surge.

If that is heresy or stupid, just say.

It would be ideal if we could come up with a simple HT delay circuit when using silicon diode rectifiers. Using time delay and relays seems a bit archaic.
