Informacja

The Ameritron AL-800 is a 1200 watt PEP output linear Amplifier that operates from 160 through 15 meters. The AL-800X and AL-800Y are export models that operate from 160 through 10 meters. Export modification instructions are only available with proof of a valid amateur radio license. The AL-800 uses a single 3CX800A7 tube in a class AB2 grounded grid circuit. High-quality Power Supply and RF components combine with an accurate peak-detecting directional coupler, front panel adjustable true ALC circuit, electronic grid current and thermal overload protection, and automatic bias switching to make this the best featured and most reliable single 3CX800A7 Amplifier available. The AL-800 and AL-800Y are factory-wired for 120 volt, 50/60 Hz ac line voltage. The AL-800X is factory wired for 240 volt, 50/60 Hz ac line voltage. All models are easily converted to other supply voltages between 90 and 250 volts ac.
