Audiophiles hifi appreciation thread old and new

I think I might try to build a valve amp. Can anyone recommend kits/schematics?

Depending on what you want....Got deep pockets? :-) I scratched my 1st appalling valve amp about 10 years ago but had the advantage I'm an Electronics Tech by trade. Later I built one of these -> http://www.world-designs.co.uk/kt88.htm

Its OK for a reasonably powerful (by Valve standards) Amp using Valves that are still in mass production but not cheap, £1150 for the basic version. there's a simpler PCB based amp that uses the sweet EL84 Valve here, same company http://www.world-designs.co.uk/el84.htm

TBH, I sold my KT88 PP amp to fund a pair of very exotic output transformers when I got deeper into pure DIY (not kit based) Single Ended Valve audio. Madness lies this way, beware!

There's also AudioNote and Glasshouse Kits worth Googling for info.

Have you worked/had experience of High Voltage rails before? Gotta be VERY VERY careful working on this sorta stuff, you really can get killed in the face (twice!) if you connect with HT rails.
