Hi,
Carnhill Transformers (http://www.carnhill.co.uk) manufacture high quality audio toroids up to 2.5kVA they have a factory about 8 miles from where I live almost went for a job there! You will be looking at a lot of £££ if you only want 1 though!

Cheers, Jim

Hi digitallake
Thanks for the reply ile give em a ring but i think 2.5 kva is still a bit too small is it possible to use 2 off 1.5 kva 75 volt transformers in parallel?
cheers
Rob

Hi,
pity 55Vac (110Vac centre tapped) is too low, site transformers are fairly cheap.

if you have two modules and are considering two transformers, why not just take the next logical step of going for dual mono instead of paralleling them? that'll be something the amps you're replacing certainly won't have.
