Ameritron AL-811H HF Amplifier USED | 12 Months Warranty
Ameritron AL-811H 800W HF Linear Amplifier,The AL-811H amplifier is an ideal linear to use. The AL-811 delivers 800W PEP with 4 x 811A valves. The excellent cooling fan runs quietly but efficiently and enables you to work contests or rag-chew. It matches the modern solid state rig and offers up to 9dB of power gain, that’s nearly two S-points. In an instant you can switch it to standby when not needed and just as quickly switch it back into circuit. The heart of the unit is its power supply which uses a really hunky transformer and components to match. Carefully designed circuitry results in 70% efficiency and the valves will happily load into 3:1 VSWR.
