[Elecraft] ASTRON RS-20A

[Stuart Rohre]

And, as someone pointed out, the RS 20 is fully capable of the supply the
peak and average demand of the K2 and the 100 watts amplifier.

The Astrons linear models are good supplies.  The only help they need is to
be run from a spike protected outlet or outlet strip, as in three or more
cases, I have seen them have either the 723 regulator chip, or an internal
MOV on the AC line taken out by lightning nearby hits.  However, the fix on
the 723 chip is simple replacement done with minimal soldering tools, and
the addition of a new MOV across the power line.
