HXL-ONE kilowatt linear amplifier built by Hammarlund in approximately 1960 or so.

The HXL-ONE is a grounded grid amplifier that uses two 572A/B zero bias carbon plate triodes (Russian Svetlana tubes are used here).

The unit is completely self-contained with an internal high-voltage (~2300 volts DC) power supply.

Frequency range is 80-10m in five bands with plate power input of one kilowatt DC for CW telegraphy operation, 1.5 kilowatt PEP for SSB, and 500 watts DC for AM modulation.

Power requirements are 100 watts standby and 1,500 watts for key down CW.

The unit measures 17" x 9.5" x 9.125" and weighs 66 lbs.
