K3: power supply for K3/100? solid suggestions?

[Brian Pepperdine]

Simply put. For thhose of us getting a K3 with a 100 watt option.....

What power supply to get? Let's not beat about the bush.. suitable p/s with
the amperage required.

I see a lot of reviews etc. and negatives on some etc. I just want a good
supply, no hum, no trouble, no issues.
I will say I see Astron seems to go from 20 amp to 35 amps with not anything
between (at least from the local ham joint), so it might be necessary (?) to
have a few extra amperes on hand, as Elecraft seems to suggest 13.8v with 25
amps and no lag?
(not trying to stack any particular maker, just thought those of us who will
need a p/s will want to get on that task solidly with no confusion as we
await K3 arrival).

Tnx

hi Brian - you really can't go wrong with an Astron linear supply. Get the 35A and have plenty of
room to power extra accessories. Get a power strip with fuses and Powerpole connectors and you'll be
set to go!

I have had great success with the Astron Switching PS...the SS-30 handles my K2/100 and KAT100 with no trouble.  Lightweight too.  I do not like the connector on the back.  It is a compression screw arrangement and not binding posts.  So, to get a good connection, you have to have a good flat screw driver with a large handle to get enough torque to get a good connection.  But, it is very light and works like a champ.  We tried to kill the station on FD and could not do it.  We had over 1100 Qs on FD running the station with the SS-30.

In our day and age it seems that Common Sense is in short supply.  If you don't have any Common Sense - get some Common Sense and use it.  If you can't find any Common Sense, ask for help from somebody who has some Common Sense.  Is Common Sense divine?

I also use the Astron SS-30 with good success. I agree that the
compression screw arrangement is not the greatest.
Here is a neat mod that I did on mine. It takes a little work but hey,
we're Elecraft guys

On the SS-30, be sure to take the cover off and tighten the 4 PC
Board mounting screws.

On two SS-30M's, I found 3 of the 4 screws to be loose even though
they had the usual drop of paint on them.
