Up for auction is a Heathkit AA-50 stereo tube amp. Please check all pictures for condition. Feel free to ask questions.

Previous owner bought it 10+ years ago, never used it. I tested it using my mono Heathkit AM tuner. I ran it for about 3 hours on the Tuner input and it sounds good. I then tested Aux 1 input and one side did not work for some reason. Then I tested Aux 2 input and both sides work. I did not test the phono or tape inputs. 

All the knobs work as intended. The bass & treble adjustments work well adding or subtracting bass or treble.

Tubes in it are USA except the 5AR4 tube which is Russian. I did not test any of the tubes on my TV7/U. One of the 7591 Tubes has a crack in the base I did see.

I didn't hear any hum but the old electrolytic original can caps should be replaced sometime in the future or not depending upon if you run it daily or weekly is my experience.

It weighs 26 lbs.
