Hi!
I'm very happy with ESO (Electra Sud Ouest) power and output transformer. They are in Toulouse and here:

They will make the iron you want (just give them datas) at reasonable price.
I bought (2month ago) a 8k/8/4 ohms 20% screen for a 18w (UL is sounding better with 20% in my 18lite) in the 60euros range.
I also ordered a 70W UL43% output transformer according to the KT77 MOV datasheet for my "route77" in the 100euros range (but copper was cheaper for this one).
The only problem i encountered was with their carrier ?hexapack? who didn't find my house in a small corsica village( hey! just ask anybody here! everybody in the village know where i live and you don't need my mobile number

)
ESO is known by french HIFI guys (ptsounlab etc..) and now from guitaramp guys (projet g5).
publicité sincère et gratuite
cheers.
