[Elecraft] AC Adapter Power Supply For KX3

[Bob Schumacher]

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,
