For those who would otherwise consider Edcor I suggest looking again at enovaz.it as their prices are close for similar spec (will ship to EU only but Italian post seems to be one of the cheapest in Europe for <2kg)

Thank you friends, for all that posts and help provided.
I think there was needed a thread like this, I suppose I am not the only european starting to work with tubes and wondering where to get those bulky transformers "locally" at a fair price. And by fair I don't mean low or cheap, I just mean not paying more than half the cost to the government.

:-)

I am happy to hear that you decided to order your trafos from a domestic (Spain) lab. It is the most wise. It is the less expensive solution.
There are not top secrets behind transformer construction. The conventional E-I laminates are made from CRGO (Cold Rolled Grain Oriented) Silicon Steel and used by 90% in all trafos. Only the output trafo core requires special laminates, from CRGO Silicon Steel again but of 0.35mm thickness. These cores are also called "M6" and the "E" laminates are separated from "I" ones. There is a gap, hidden into bobbin so no visible, between E and I laminates. M6 cores are not saturated so easy and you can discern a such core very easy. Laminates are very thin and by looking the core from above you can discern a separating line (gap) only in one side. That shows that all E laminates are placed from the one side of bobbin and the I from the other. In conventional cores E laminates are inserted from both sides of bobbin and at the end are inserted the I laminates from both sides to fill the gap remaining.
To not worried so much my brother from Spain , my Greek supplier sell the M6 (B = 1.7 Tesla) / 100W (350mA max primary current) output trafo for 162 Euro + 23% VAT of Greece = 200 Euro with open frame or black powder painted covers. For nickel covers, he charges additionaly 5 Euro per cover.
He also construct with the same method the chokes. A M6 / 10H / 310mA choke costs 50 Euro including 23% VAT.

I had a recommendation for OEP in Oxford UK from somebody who had some custom made transformers. He said the designer was very clever and easy to work with and came up with a great product. They supply a whole range of transformers to the usual UK online suppliers like Farnell, and hide behind a fairly anonymous image. They have a small range of tube transformers, like these:

OEP

Where I think their big strength may lie, however, is in the smaller audio transformers. They start cheap, as in the 1+1:1+1 600R to 600R at 10

Search Results | Farnell United Kingdom

I'm wondering, though, if they could make something more fancy with nickel etc. They may be making moves in that direction - here's a DAC O/P transformer with mumetal core listed under new products.
