That tone lizard site is a lot to take in ay once, but very cool. Seems a very straight to the point approach. However, Im looking more for a beginners guide. Not that I dont understand what is being said, but I like to be very clear on the hows, whys,and what not. (Why would matched tubes be preferd or not, instead of the guy at the music store sayin, well these are the most expensive....must be the best.)
