The HT supply for my 4CX250 amps (x2 on HF x1 on 4 & 2m) uses a toroidal 
transformer made to a spec. drawn up about 10 years ago by one of our 
club members by Avel (http://www.avellindberg.co.uk/)  
<cid:part1.04040205.09030708 at btinternet.com>.
The transformer gives about 2.2kV off load, this drops to about 2kV when 
fully loaded by the HF amp. We purchased several of these transformers, 
I can't remember the price but they weren't very expensive.
