Not Too Great  Time owned: 6 to 12 months
I bought this one to power my ALS-500M, which it appears others have done as well. It worked fine until just the other day. I was listening on 40, linear was powered off, but the 4275 was on. In fact I had not transmitted for at least 30 minutes. I heard a little "plink" which sounds similar to an auto switch powering off. The Fault light came on, and I attempted to power it off. No way, no how, would this power supply power off until I pulled the AC plug. After waiting about an hour, I plugged the AC in again, and right off the bat the supply came on, with the fault light. Of course I had made sure the power switch was still off. Will update if I ever figure this out. This only powers the linear amp; my Kenwood is on an Astron power supply.  
Product is in production.
