Replacement Toroidal Transformer EVOii 500

[oldslapper]

Need a replacement for the above.
Ashdown quote £160 for replacement before labour. 
Before I go down that line, has anyone any suggested alternative sources please?

 Thanks for any advice.

Any company that produces transformers. Cost is probably similar and hunting the exact specs costs some extra.

It may be worth contacting 

Demeter Windings , in Chelmsford.

Very reasonable,  I've had very good service from them in the past to repair my Trace Elliot valve amp.

Airlink Transformers  Harlow are good... I've used them for toroidals for US to UK voltage conversions on a GK 800RB & a 400RB
