Hi Tre'
Thanks for your reply. I used an Edcor XPWR010, with the HV secondary of 750 V, 175ma, and of course a center tap.
Best wishes,
David

Is there 750vac at the secondary?

Hi that is the spec provided by Edcor, though I can't check it again tonight. Is there a rectifier tube compatible with the 5V4G that has enough voltage drop? Would that work?
I was going to ask you about the DCR of the power supply choke and the DCR of the primary of the output transformer and also the value of the first cap in order to figure out why the voltage is high but I guess it doesn't matter.
I think the rectifier with the largest voltage drop is the 5r4.
