I finally have a free weekend. We are ready for the demo at work, and I have just finished building the new Tubelab SSE (simple single-ended) PC board. It rocks! I have been blasting this thing with everything from Roberta Flack to Metallica. It is hard to believe that I am listening to $18 output transformers. If I don't find anything wrong with this in a few days, I'm sending the board out for duplication.
