    • "Nice power supply but one major problem" by kcjaeger on 2/23/2010
      Regulated 13.8VDC Power Supply - 20A Continuous
      Overall: 1.5 out of 5

      Quality:

      First the good news: This was a very nice supply when it was new, it worked very well, the output was clean and stable. It worked great on my Ham rig, I would have rated it 5 stars except for the bad news below. Now the bad news: After 14 months it failed by voltage going excessively high, resulting in It burning out my $450, 1 year old, Quad Band FM Ham transciever. This SUPPLY NEEDS OVERVOLTAGE PROTECTION. I replaced the bad transistors and added a overvoltage protection circuit and it now is working again. My $450 radio however, is beyond repair.
