[Elecraft] My power supply solution

First off PS are widely available and there is no incentive for 
Elecraft to expend design effort.  IF they decided to offer one it 
would likely be a repackaged PS from a vendor.  And that might be 
desirable to many who want a nice visually integrated station (aka "pretty").

MY station runs 18 bands from 600m thru 9cm at home.  I power the 12v 
equipment with a 50A Astron rack-mounted supply.  It feeds thru about 
12-foot of #4 welding cable to the 30A main Buss fuse at the 
distribution terminal strip.

The 28v equipment runs from two supplies: a Motorola CCS 500w 
repeater supply and a 8A adjustable 22-30v supply (for relays, 
etc.).  13.8v drops to about 13.3v under 25A load.

MY 6m QRO SSPA runs from a HP 50v-50A switching supply (230vac 
input).  And my 2m-8877 runs on a 4kV 1.5A modified commercial supply.

I have a B&K 0-30v 3A bench supply and 0-15v Astron VS-35M on the bench.

The dish runs with a 28v 50A military surplus PS.
