[Elecraft] Walwarts - linear supplies

[Larry (K8UT)]

Two years ago, I embarked on a "wallwart-ectomy" in my shack, removing 
all wall warts and replacing them with DC power cords that connected to 
fused dc power strips, connected to a single shack linear supply. Band 
decoder, PC speakers, SDR Rx, wavenode wattmeter... none of those items 
have their own power source any more.
