Thanks for the nice words, guys!

I believe we ended up using 5150 + Dual Rectifier. Quadrupled. As far as I remember it was this modded version of the 5150. Scaled down to deliver only 50watts... But hey, I've got a 6505, and seriously I can't tell much difference. The 6505 sounds rad!
Yeah, I've used Valvestate on many albums, although never ONLY Valvestate (oh, except for Beyond Twilight), but in combination with a good, fat tube amp, I really like it! The Valvestate is so "tight" and "twangy", which I often miss in big, fat tube amps.
