Wayne has said that 14.2V is desirable (as read on the display, so
~14.4V at the source AND the input connector at the radio). This
provides a more clean signal.
It's also important to not allow voltage sag under load (for the same
reasons).
Just make sure that if the power supply causes noise, that you can
return it without cost. Then your decision is switcher vs analog, each
work well; each have issues or 'features'.

Hi Ken
Thanks for the info.
I am not in a rush yet. I noticed that the voltage is 13.4.. Maybe a
little higher might be better. Not sure on the last point.
I will check what else they make

Richard,
I use an IOTA DLS-55 SMPS power supply (
https://www.iotaengineering.com/dls55.htm). It provides 55 amps, doesn’t
produce RFI, is audibly quiet, and rugged. The dimensions are 9.7" x 6.7"
x 3.4" and the weight is 5.0 lbs. Mine is on 24/7/365. IOTA also makes
them in other output voltages and currents.

I need to get a new power supply for my upcoming K4 and accessories
before
my present 40 year old supply goes belly up.
I want reliability and no fussing , fixing or modifying things. Any
recommendations.
I heard that some of the old brands are not what they used to be.
Thanks,
