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 ?

Call me old fashioned, but I like a good quality transformer between me
and the mains.  Mind you, we have a mains voltage of 240 VAC down here.

A transformer for me, and no SMPS for my K3.

I'm using an Alinco DM-330MV switching power supply for my K2 with no
problems. It has a control that allows me to move the frequency of any RFI I
encounter from the supply, but I've never heard any.
