I´ve decided to build a simple EL84 amp as my first tube project. This first project will be more about learning than to build an extremely good amp.
For instance, I found a cheap universal OPT at a great price (About US $25 each): http://www.demostenes.no/endr1be.asp?Kode=3956
I´d really like to use either those trannies, or a couple of Hammond universal OPTs from the 125x line, maybe the 125B would be suitable for an EL84 SE amp and the 125C for a PSE amp with two EL84 per channel?
The Hammond OPTs mentiones cost about the same as the first one I linked to, which is made by an italian company called Novarria.
What I´m looking for right now is a suitable schematics. I´ve read the thread about SE EL84 amps and really like this one:
Please give me some advise. I´ve done some calculating and it looks like it would cost around US $100 to build the amp in the picture.

An externally hosted image should be here but it was not working when we last tested it.

Here are 3 interesting circuits I found at tubebuilder.com

The one with the EF86 looks like it might be the Mullard 3.3 circuit, which I have listened to mono blocks. The set of 4 transformers was $400, hand wound in England. Review in <www.audioreview.com>
