Tom:

I went through the same exercise yesterday, but for a different 100W rig.
The RS-20 can supply 16 amps continuous, 20 amps peak.
The RS-35 can supply 25 amps continuous, 35 amps peak.
Check the max current drain on the K2/100 specs and pick whichever is
appropriate
(I'd suggest using the "continuous" rating).

You can find the Astron supply specs at:

Note: one of my dislikes with the RS-35 is that it hums rather loudly.
Well, noticably anyway.  At least it's 60 Hz and not high frequency.
I assume the RS-20 is quieter but I'm not certain.

Of course when sizing your supply consider what else you might want to
run in the shack simultaneously.
