Can't remember, I will have a look tomorrow as its still sitting on a rack in my old workshop, think its either 2 x 0-18V or 2 x 0-22VNice! Which Talema transformer did you use?
I do like that build, very neat.
Anything will do - it only draws about 10mA per channel, so even 1VA would work. Transformers don't get much cheaper below say 10VA, so that would be a sensible size, but if you have some other size in the parts drawer, or see a bargain, it really doesn't matter. Bigger does little harm, but is a waste of money....and please let us know the VA rating as well!
