[Amps] Custom HV transformers - UK

[Mark Hill]

Folks,

Any recommendations as to UK-based companies that will custom wind single 
phase, multi-kVA HV transformers suitable for valve PA's?

I have had a quote from Express Transformers in Runcorn which, although 
fully compliant with the spec. I sent them, seems somewhat pricey to me.  I 
have no benchmarks to guide me here, e.g. price per kVA.  Any help appreciated.

Regards.

Mark.
