Heathkit SB220 Linear Amplifier
Approx. 1kW on 80 – 10m bands. It has been modified for QSK with vacuum relays although will work with the usual PTT input. QSK means you can receive between dots and dashes. Comes with 2 spare 3-500Z tubes, useable but don’t make as much power as the tube in the unit itself. $750.
