Recently I came across W5KUB´s review on switching power supplies on Amateur Radio Roundtable. In this case he reviewed the 30 AMP Jetstream JTPS32MAB 12V switching power supply. These units are sold for a fair price compared to many others on the market. I decided on this one and it´s on order since the review implied the unit is very quite while running. I will post my personal review later down the road.
