Since you are not dealing with any real HV any 600V rated wire will be fine
as the actual breakdown is around 2-3 times that. They werent that fussy
back then.
USA made VOM test leads are a good source of HV wire up to 5KV or so
depending on their original use. Ive used them in many 2-3KV supplies over
the years. Old ones can also get brittle so be carefull what you get.
Teflon is good for HV BUT it is very easily nicked and damaged.

Subject: [AMRadio] Transformer Lead Dress
Hello,
I just stripped out a basket case VK II transmitter for rebuilding.
Most of the transformer leads are brittle and even carefully removing
them thru the chassis hole, I can feel the rubber inner jacket breaking
up.
I would expect to replace the wires near as I can get to the windings.
The plate transformer will need good HT wire.
I have quite a bit of different sizes of silver teflon.
for most of the windings but not quite sure what to do about the HT
wires.
This is a project transmitter, not a restoration.
Suggestons? Sources of suitable wire in an affordable put up. I have
other large transformers with the same problem as well.
Thanks,
Bill, KB3DKS/1
