Default Power trafo...

Hey guys,

Following on from this thread : First foray into tubes!!

Seeing as transformers are sparse pickings here in Ireland, I contacted a crowd up in Belfast by the name of Antrim Transformers, who will hopefully be winding me a toroid with the following :

Secondary Windings:
325-0-325V @ 0.3A rms (red-yellow-red)
0-6.3V @ 6A rms (green-violet)
0-5V @ 2A rms (blue-grey)

Those should be more than adequate (I purposefully asked for a little more headroom on the 6.3 and 5V lines for any such ancillaries as LEDs) for a 12AX7 and 2 6v6GTs. Will be interesting to see how it turns out.

About 130 shipped to Ireland.

Also, can anyone recommend some European made o/p trafos?
It's all well and good in the states, or even mainland europe but Ireland really takes the cake. Anyone used that german chap's ones? Ask someone First, I think he was

Regarding transfomers, I believe you mean Ask Jan First (www.askjanfirst.com)

I do business with him for many years now, especially in buying valves.
Some months ago I bought my first output transformer from him, the cheapest PP transformer he has to offer and it surprised me a lot! Great dynamics and overall amazing sound quality. I can only imagine how the more expensive and better rated transformers will sound, and why should I spend more money on them, especially with these entry level trannies.
The prices on the entry level (cheaper) ones can't be beaten, at least comparing with the manufacturers I know of and if taken into account the quality/price factor, it's hard to say anything bad!

His shipping rates are veeery good as is his service, very fast and thoughtfull.

Just a personal opinion here from good experience as a customer.

That's the guy! Frag Jan Zuerst. I think I'll be going with his good ones, on the basis that they have favourable reviews here, and that they won't break the bank if not!

Sowter in England is a source to consider.

For O/Ps?

Bear in mind this is my first amp, and hence I'm completely on your recommendations!
