I did make a request for this sort of info in the thread before this one
I too have been learning a lot from the questions Dave has been asking. I'm edging closer to asking my own, too!
I would definitley like to see a beginner's info section - and I think what Beechy has done here falls into that. I'd still like to know what a soundstage is.

I also think a section on valve equipment for someone who has never had valve equipment would be good. General things you need to know to be able to use the kit, and I don't mean fettling.
