• HF linear amplifier AL-800 for amateur radio

The Ameritron AL-800 HF Amateur Radio Amplifier is a 1,200-watt linear PEP output amplifier that operates from 160 to 15 meters. The AL-800 amplifier uses a single 3CX800A7 tube in a class AB2 grounding circuit. The high-quality RF power supply and components combine with a peak detection directional coupler, a front-panel adjustable ALC circuit, automatic polarization switching, electronic gate current, and thermal overload protection to provide the highest performance. best amplifiers 3CX800A7. The AL-800 HF amplifiers are perfect for the amateur radio and are wired in the factory for 120 V, 50/60 Hz mains voltage, but can easily be converted to other power supply voltages between 90 and 250 Vac.
