    • "Great pwr supply" by payneengineering on 3/19/2013

      First and foremost, I have been the proverbial stick in the mud when it comes to switching power supplies. However, after having this supply, I am totally impressed and then some. I not only deal with broadcasting, but am a amateur radio operator, and run radios from 1.8 to 460 mhz. No noise, no spurs, no sagging. 100% solid. My ham operations include a variety of hf nets. I run a 120 watt radio, full bore, and the power supply delivers. My old faithful 30amp supply weighs in at 55 pounds. Compare this to the Tenma, which is lighter than my hf rig. If you're counting the power you use every time the power bill hits, I can tell you, this will help. I could go on, but suffice to say, a awesome product.
