TF110-48/UL in the UK?

Boscoe · 23rd January 2011, 12:10 PM

Currently contemplating a tube project and wondered if that output transformer was available in the UK? This is my first tube project so I don't know many suppliers and such.

Thanks

By any chance, are you considering building an "El Cheapo" (schematic attached)? That "piece of iron" ceased being a bargain some time ago. Sowter is UK resident and makes a superb, if costly, product. Their model U064 would work for a triode wired setup, as shown in the drawing.

You will have to work the expense numbers for yourself to see if importation from the US makes sense. The "budget" O/P trafo I currently recommend in building an EC is Edcor's model CXPP25-6-7.6K, which is substantial enough for use with UL mode "finals".

Okay nice one thanks but I'm doing a different design to the 'el cheapo'.

Post the schematic, please.

There you go. This is only an idea it can be changed to a different design.

A UL mode PP pair of "12" W. tubes, like the 6BQ5, is good for approx. 12 honest W., in combination with a separate phase splitter. Self splitting limits the O/P to 1/2 of yield from a separate splitter. The claim of an 8 W. O/P is VERY ambitious.

Okay fair enough, I was actually looking for a push-pull design could you help me out with that?

Hammond stuff is available in the UK from www.bluebellaudio.com
Edcor will ship to the UK without problem.
Sowter stuff tends to be very pricey, and I had a bad experience once.

Hey

I have used some of Mike's transformers.

He is updating the homepage in the moment, so there is some dead links.

Were these formerly supplied as "Danbury" transformers? I used a good few of them before Maplin stopped stocking them.
