I have a
limited quantity of AM2060 power supply/ audio amplifiers complete with
ONE CX-4655 interconnect cable that connects the AM2060 to the PRC-25
or PRC-77. This combination is also known as OA-3633A/GRC. The AM2060
operates off of 24V DC then provides low voltage DC power to the radio
and a audio amplifier for the speaker. The unit also provides remote tuning
for the MX6707 antenna tuning unit.
This is the lowest price that you will find anywhere on the web.
