Hi Mike
Yes, the working voltage is much lower.
I haven't done the calculations on the winding resistance but I would expect it to be something like 10K.
The transformer feeds a valve rectifier. Then smoothing is done with a C R C filter. The resistor being 250K.
I am not sure yet what the working voltage is. 3KV is in my head but I cant remember where I got that from.
For now I am just interested in the peak off load voltage. As the EHT transformers insulation will have to withstand that plus a margin.
For an overwind I try and use as thick of wire that will fit.
For a given width of winding the the thicker the wire the lower number of turns per layer.
This helps to reduce the voltage difference between layers.
