The Henry 2-K (sometimes advertised as "IIK") amplifier used a pair of Eimac 3-400Z triodes to run 2000 watts PEP input on SSB, as well as the legal limit on CW and AM. It was available as the desktop model (shown), with external power supply, or with a power supply floor console. The 2K covered 80–10 meters.
