I need a transformer for an EP1 - if you have seen any of my other posts, transformer spec'ing is not my strong suit.

This is what I found that seems to be in the ballpark, if someone could verify that I am on the right track that would be swell. I think I should be in the ballpark of the 140vdc

Thanks

that has solid state rectifiers so there will be less voltage drop after the secondary,

divide by root 2 to see perfect world voltage,

140/1.414= 99 V

there will be DCR losses so make it 100 VAC sec plus your 6.3 wind.

what is the footprint?

measure the core, probably EI 75 or a close metric lam.

there is not a ton of extra room on board and you probably do not want to drill holes in a vintage unit.
