This discussion gives me the opportunity to correct an opinion that I
earlier posted on this list. Some long time ago I said I didn't much
like the Watson W25-XM switched supply because of RF noises which
always contrive to arrive on frequency at the worst possible
moment. I advised someone on this list to think twice before
purchasing a Watson switched supply.
However I now have the tiny Watson Power Mite NF, a surprising and
very thoughtful birthday gift from my wife. It is much quieter in RF
emissions and anyway has a front panel control to shift the switching
frequency in case hash does arrive on the operating frequency at a
bad moment. The variable-speed fan is moderately quiet too. This
supply powers the K3 (or K2) just fine.
I would prefer to have a big linear PSU, of course, but my present
operating conditions are much better served by this small and very
light switcher.
