Ameritron ARB-700 Discontinued
Amplifier Relay Buffer
The Ameritron ARB-700 Amplifier Relay Buffer serves the same function as the isolation relay recommended by many transceiver manufacturers, but has no moving parts to wear out or reduce T/R switching speed. It helps protect the radio from damage caused by keying line transients or excessive current and voltage.
Any transceiver that provides as external power amplifier control line may be set to control any amplifier having a relay voltage under 200 volts and 200 mA when the ARB-700 is used.
This device comes with two RCA phono plug to RCA phono plug cords and a red/black power cord. This item is discontinued
