The new version is only a cosmetic change according to earlier replies on this very thread.
I would like to see a Woo6SE vs Traufomatic shootout. They are similiar topologies. The Woo has against it that it uses TV tubes, the Traufomatic probably has a better OPT's (since that's their forte'), but the Woo6 has more power. So it would be an interesting comparison.
