[Elecraft] Power supplies ..

[JACrux]

Recent experience here suggests that finding a switcher that does NOT cause 
RFI and fan noise problems is a problem.  
I just went back to using a boat anchor industrial linear supply weighing in 
at around 40-50 lbs for that reason. Unfortunately it came with large 
terminal bolts, no PowerPole connectors ! But it works and there is no noisy 
fan and it will certainly run a K3 as well as a K2 and my Omni-V.9.
MFJ offer a heavy 25 amp+ linear supply, but why oh why is it only 110 VAC 
input ?
