Default transformers for ClassD amplifier

I'm searching two C-core transformers for my Eco Tec 600 watts modules in Europe (spec:
Primary 230Vac, 50Hz
Secondary 70Vrms, 9A (for full power, you can derate this for lower
power)
Auxiliaries 15Vrms, 0V, 15Vrms auxiliary secondaries (centre-tapped) at
0.3A. I've contacted the Avondale Audio but they don't have them no longer.
Someone could help me?
Thank you

You need someone to build them to your specs,,, in italy we got Delbini [ near Bergamo IIRC - http://www.dte-trasformatori.it/frsindex.htm ] and Fiat Trasformatori [ no, it ain't the car maker, it's in Roma - http://www.fiat-trasformatori.it/ ].

Dear Basstard
thank you for your reply. I call the FIAT transformers the next week. Did you ever buy something from them?
Regards

yes, I bought a small toroidal trafo in 2007 and they were very quick, I called in at lunch hour and then the very next day it was ready and I went buying it. You can order by phone. They ain't exactly cheap and I've seen better transformers around but they're the only company I know that can do you toroidals to your specs. A search for "trasformatori" on www.paginegialle.it around your hometown might be worth a try too.

Probably I'll ask an estimate to Bartolucci and Elettronicanovarria.

yeah, I brought a trafo from novarria, nice build quality and pretty cheap but I didn't remember they also realized transformers on specs.

Yes, on their website there is this possibility. Obviously their transformers will be cheaper than Bartolucci. I received a very good offer from Canterbury UK but, in this case, they are toroidal.

I mean:http://www.canterburywindings.co.uk/. Terry Monaghan has a very good reputation and is very competitive (195 euro for two toroidal transformers shipping included).
