Buying notes
Heathkit tube amplifier, sold as a kit. Build quality varies with the original builder's skill; inspect solder joints carefully; cold joints and poor wiring are the main risk. Tube complement condition. Check both channels produce output at matched levels. A well-built AA-100 is a solid performer; a badly built one is a liability.
