Used Alpha 8410 HF Linear Amplifier

This top-of-the-line, self-contained manual tune amateur radio amplifier was purchased new and it is in “as new” condition and certified to have never been used on-the-air. With two 4CX1000 Tetrodes, it is more than capable of the full legal power limit of 1,500 watts peak power output on SSB, SSTV, RTTY and other digital modes, or FM with no time limit. It is compatible with popular transceivers and exciters capable of driving it with 50-65 watts peak RF for 1.5kW output on all authorized bands form 1.8 to 29.7 MHz. It is capable of full CW break-in, QSK and all digital modes. The built-in protective functions minimize the probability of accidental damage to the amplifier or its power tubes (if tripped, it goes to Standby mode). All documentation, parts and shipping containers are included. This unit has been stored in air-conditioned home, non-smoker environment.
