I'm using a DIN rail mount commercial supply made by Mean Well, model
MDR-40-12. It's a switcher, it's small, and I've had no noise issues.
It's output is adjustable from about 12 to 15 Volts (screwdriver
adjust). The continuous current rating is 3.3 Amps.
You can find them through a Google search. I bought mine from TRC
Electric though I see that Mouser and many others also have them. Being
a commercial supply, you must provide your own line cord (attaches via
industrial screw terminals). TRC had them for under $25 though their
shipping was a bit steep.
I'm not the only one I know of using this model supply with a KX3. I've
heard no complaints.

Elecraft does not sell a 13.6 VDC "AC Adapter Power Supply" for the KX3. This
is a very common product and there are many
alternatives on the market. Most of us have drawers full of these AC adapters.
However, most are cheap, noisy switching power supplies.
Is there a recommended KX3 power supply that provides sufficient current to
obtain the full 10 Watt output and yet not add to the nosie floor of the
receiver?
Thanks,
