Astron RS-35M power supply 13.8 VDC at 20 amps continuous, 35 amps peak. Current and voltage meters on front panel. Bought it new about a month ago for use with my Triton/544, but now using a different rig with lesser power demands. Supply is as-new, in original box. Haven't even soldered anything to the lugs. $110 plus shipping. --Andrew, NV1B
