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

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...

Thanks, Barry - have not heard of Kikusui before. Checked EBay,
actually quite a few Kikusui items there. Fairly small current output
it seems, but nice-looking equipment with a fair amount of hands-on
control. I think I'd need a manual.

As far as building one goes, I tend to be a very frightened tinkerer.
I have no reliable test equipment per se, save for a couple of simple
analogue VOMs, and relatively poor soldering skills. I know, I'm in
the wrong hobby - but I just like listening to radio, and I'm pretty
happy to let others do most of the building :-)

I do like messing with antennas, though...
