Nice Ten-tec 420 Hercules Ii Hf Ham Radio Linear Amplifier Solid-state /mobile
I Unboxed a Ten Tec OMNI VII The American HF Radio Built for Remote Operation
It was in use with a companion Ten-Tec OMNI VI+ HF Transceiver, but I have not tested it. A small Remote Control unit, model # 9423 was also available for remote control of the Hercules II. This Hercules II Amplifier came with the companion Ten-Tec model # 9420 AC Power Supply, which provides 13.8V DC at up to 100A output 20A is available for the HF Transceiver, if needed.
