[Elecraft] Linear PS Recommendations

[Edward R Cole]

I blew up the LM-723 in my old Astron VS-35M  by trying to use it as 
a battery charger quite a few years ago (I bought the Astron to power 
my TS-180S in 1981).  A year ago it failed to output and blew the 
fuses.  Turned out one of the rectifiers shorted.  I replaced both 
and its working fine as workbench PS.  I guessed the output pass 
regulator transistors shorted so bought four.  Now I have four spares 
(2016-1981 = 35 years and counting).

My workplace (retired seven years) used a bunch of Basecom-20 which 
were identical to Astron RS-20A which all used the LM-723.  My guess 
Astron markets a lot of PS that are relabeled.

I use a 50A PS for powering my station (Has TAIT Two-way Radio label 
but meters are labeled Astron; guessing RS-50M).  It maintains a 
charge on a 17AH gel-cell which I use to power by station 10-MHz OCXO 
reference.  It's run 24/7 for years.  Much newer than the VS-35M.
