Thanks Peter and Arthur - right now and foreseeably, my total demand
at maximum is probably 3 amps. One main radio (Icom R75 - maxes at
about 1 amp), a MFJ-1026 (500 - 600 ma) and maybe one other small RX
or dsp unit at a time (1 amp max). All the other things I have do
just great on 115 VAC. This, after 4 decades of s-l-o-w collecting!
I have no TX and do not intend to resurrect my ancient ham license, so
that sort of larger drain will never happen.

So, at 5 amps continuous on the unit I am thinking about, that will
already give me another 100% of headroom to play with. I know I'm a
bit odd in this respect ;-), but I don't collect stuff to run
simultaneously (My entire active shack at any one time fits on 3
square feet of tabletop).

I could get a ~12 amp I guess, but that would be considerable overkill
for anything I can foresee. Not figuring on the Pyramid any more.
You guys and some research have pretty much talked me into Astron :-)

You might try checking out other brands. I have a Kikusui I got locally for
a very reasonable price and it is a very nice power supply (0-18V, 4.5A
max.).

There's a nice Kikusui on eBay right now - item 320485731691.

Just a thought. HP power supplies are also plentious. I have an Astron
RS-35M and are well pleased with it but I think for your purposes, it might
be overkill.

You could always build a nicely-regulated power supply as well. It isn't
hard to do...
