For sale is my Ameritron AL-811. This amplifier is rated up to 600 watts of power output, however I’ve run it to around 350-400 depending on band and drive level.??While I am not aware of any issues with the amp, I have not driven it to its power limits.??Designed with three rugged 572b tubes, the AL-811 is built to last and offers exceptional performance across HF bands from 160 to 10 meters. The three included/installed Russian tubes are in good shape, and I’m also including four new “matched” Chinese tubes in a box (not shown) that seemed to operate well when tested for several minutes in the amp.

The Ameritron AL-811 features easy-to-use controls and comprehensive metering for monitoring power output, plate current, and grid current, allowing you to fine-tune your operations with precision. The amplifier's automatic bias system reduces heat and prolongs tube life, while its solid state protection circuitry guards against high SWR, excessive grid current, and other potential issues. Whether you are a seasoned operator or a newcomer to amateur radio, the AL-811 will provide the power and reliability you need to make the most of your equipment.

Sold as-is with no returns or refunds.??Due to weight, size, and the potential fragility of trying to ship tubes, I have no interest in attempting to ship this.
