[Elecraft] Power Supplies for K3

[WB4JFI]

I have used one of the Powerwerx supplies with a K3 for a couple of years now.  It works great, with very little problems.  When I got mine, they still had a switch set to 220VAC, and the output was low until you changed it to 120VAC.  Instructions were included regarding that.  Mine also had some sort of non-conductive finish on the binding posts in the back, which I had to remove with sandpaper.

I doubt that you will have these problems, however.  This will be the third field day that a local club uses my K3 and Powerwerx supply for the CW position.  MUCH better than the monster Astron.
