To all who responded. The power output (Voltage or AC/DC) and Wattage are unknown. There are no markings on this thing. There is one connector, a two pin MS threaded connector. It shown in the picture. Sorry that the picture wasn't better. Is there a photo of the PRC-47 unit available? Tom > 400 cycle PRC-47 power unit? > > > > Ray F/KA3EKH >
