They seem pretty good to deal with, replied quickly and efficiently.
So many thanks and I will be able to get my plates down to 465v.
All the other voltages are good now I have adjusted the droppers.
I haven't put any snubbers on V2 yet.
I will post some pics when I get the zener in and I get it tidied up a little.
So far sounds great but I have had it turned right down at home...
