[Elecraft] Power supply for 220 VAC

[Tom Hammond]

Ken:

The Samlex 1223 switching P/S is 'jumperable' for 120/220 VAC and 
it's not terribly noisy (RF-wise). In fact, many users report no RFI 
from these supplies.

If you do notice some RFI, I have some info on added filtering for 
this supply available on my website at www.n0ss.net

I have one of these supplies and have been quite pleased with its performance.
