Heathkits

[mhardy6647]

Other options include Welborne Labs (very nice but a little pricey), S-5 Electronics (a cheap, easy to build tube stereo amp), Consonance (appear to be quite nice kits from Hong Kong), Trancendent Sound (OTL amplifiers), Velleman (all kinds of things). There are also 'semi-kits' (typically a PC board plus parts list) of various sorts from Pass Labs (Nelson Pass), AKSA (solid state power amps of some repute), and Hagerman (well respected phono preamps -- tube and solid state).

BTW, Lots of kit gear at my house: Bottlehead (built by me and/or my kids), EICO and Heathkit (the current ones not built by me but still cool stuff), and some semi-kit diy (including speakers).

You should be able to find websites and/or distributors for all of the above on Google without much trouble!
