Using one of these to power a uniden 980 ssb and another one to power a RM kl203p amp as my base radio with no problems at all! I'm seeing about 85-90 watts AM and 150-155 watts deadkeys 1 watt swinging to 4.5 on am and is set to 10-11 watts peak on SSB. Thanks copper! By the way all of my setup came from copper including the push up pole and Maco 5/8 GP antenna.

Bought this from another retailer, but will advise you not to push these Pyramids above 75% of their rated amperage, based on personal experience and what I have heard from others that have purchased this particular brand. I hooked up an old 2-pill at 150W PEP that draws about 12 amps and it runs fine. However, my friend brought over a brand new RM Italy that peaks 225W and draws about 16-18A on a 32A Pyramid supply and it runs fine on his supply, but it made this unit shut down unless I stayed on AM and kept my mic gain way low. With that in mind, as long as you stay under about 75% (15A in this case) they perform well, are decently cooled and solidly built, if somewhat heavy. This unit weighs about 22 pounds. These are the 2 reasons for my 4 out of 5 rating. For the price, not bad.
