There was such a tremendous amount of discussion (30 pages - see link) about Frank's Ultimate Pre, I thought I might see if any U.S. DIY builders had undertaken it and, if so, were there easily-available commercial transformers that you found suitable for the power supply.
I guess that's a pretty wordy way of saying "I'm thinking of playing with this for my next project and can't decide on transformers."
