The HT-41 linear amplifiercould be used with exciters having 20–100 watts output, although it took at least 60 watts to drive the amp to full power. Input power was rated at 1200 watts PEP on SSB, 700 watts on CW, and 350 watts on AM. The HT-41 used a pair of 7094 tubes in Class B grounded-grid. It was styled to match Hallicrafters’ HT-37 transmitter. The plate and filament switches on the amplifier pictured are not original.
