[Elecraft] New 30A power supply on Elecraft order form

[drewko]

My K3 fan rattles ever so lightly from time to time, it's a little
annoying. But the Powerwerx fan noise is just the sound of the air
flow. It ramps up as ambient temperature and draw increases. I notice
it in the summer when the shack is 80-90F. In winter, with shack temps
of 50-60F, all the fans are quiet-- computer, K3 and PS.
