I need a good power supply for my 5000A. I am currently using a MFJ 4245MV. It does a good job at its primary function of providing power; however, after years of listening to the LOUD fan, I am looking for something that will be silent. I know that many recommend the linear Astron supplies (RM20, RM30, RM70 etc); however, I have no idea how quiet they are. My requirements: 1. Its operation is SILENT!!!! 2.Output voltage adjustable (at least between about 10 and 14 volts) 3. Provides 30 to 40 amps output continuous 4. Has no RF noise/hash within the Ham Bands I could probably live with a fan that was temperature controlled and only came on when the unit got hot. Any suggestions? 73, Tim K8XS _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
