[Elecraft] K3 - what power supply are you using?

[Bill]

I have a very large deep discharge battery and the West Mountain 
distribution and charging stuff. This is why I am actually considering a 
20 amp supply. The battery picks up the slack - and when the power goes 
out (which it does all too often here) you keep right on talking. I 
question the continuing need for a 35 amp supply with this system.
