Heathkit AA-100 Tube Amplifier (1960)

First a boatanchor, now a fossil, the Heathkit AA-100 tube power amplifier shone when it came out in 1960: 25 watts stereo, cheap, ‘sweet’ output tubes, and a ton of inputs. Plus, the fun of building it yourself from parts. An AA-100 surfaced a while ago and landed on the Retronics workbench.
