Information

The AL-811 is a grounded grid linear Amplifier developed by Ameritron using low cost 811A power triodes. It operates in class AB2 for SSB and CW. 1. Fast Warm Up Time: The 811A tubes take approximately 3 seconds to warm-up. 2. Long Tube Life: The 811A tubes are long life, reliable transmitting tubes. 811A tubes offer rugged, reliable operation even on RTTY and SSTV 3. Tuned Input: A Pi-Network tuned input matches the 811A tubes to 50 ohm exciters. 4. Two Illuminated Panel Meters: The AL-811 has two illuminated panel meters. The Grid Current meter provides a continuous reading of the 811A grid current to indicate proper loading of the Amplifier. The other meter switches between high Voltage (HV) and Plate Current (Ip). 5. Safety Interlock: Removes AC from the unit when the cover is removed. Never attempt to defeat this switch. 6. Operate/Standby Switch: Used to remove the Amplifier from the RF line while filament and plate voltages are maintained for "barefoot" operation. 7. XMT Indicator LED: Provides a front panel indication of proper Amplifier keying by the exciter during operation. 8. ALC Voltage: The drive level is detected to provide a negative control voltage for the exciter. ALC prevents overdriving of the linear and reduces distortion from excessive drive power.
