Connect the RF output of the transmitter or transceiver to Connect the shortest possible ground lead from a good earth the RF IN connector on the rear of the AL-811H with 50 ground to the GND terminal. ![]() ![]() Note: the AL- air flow unless the fan exceeds the AL-811H fan CFM by a 811H transformer allows operation on 100V line voltage in factor of 2:1. Do not 'assist' the appropriate setting indicated by the chart below. The ALC line can then be connected reach the power transformer as long as the AL-811H's top cover and the ALC control on the amplifier can be adjusted to a point is in place. The interlock switch stays closed to allow AC line voltage to ALC line disconnected.It operates in Domestic model (AL-811H): 160, 80, 40, 30, 20, 17 and 15 class AB2 for SSB and CW. The AL-811H is a grounded grid linear amplifier developed by Frequency Coverage Ameritron using low cost 811A power triodes.The AL-811HX export model is pre-wired for 240V operation and is supplied with 8 ampere fuses. If you are rewiring the AL-811H for 240/230/220V operation, you must use 8 ampere fuses. NOTE: Fuses supplied are for 120/110/100V operation (Models AL-811H/HY).Heavy duty power supply and RF components provide long service for components. The AL- 811H uses four 811A tubes in a class AB2 grounded grid circuit. HF POWER LINEAR AMPLIFIER INSTRUCTION MANUAL The Ameritron AL-811H is an economical 800 watt PEP output linear amplifier that operates reliably from 160 through15 meters. ![]()
