[Elecraft] K2 on order!

In addition to the smaller Astrons, Ten Tec makes a small 11-amp supply: the
model 937. It's about the same "footprint" as the K2 but about half as high
as a K2. Remember, you're looking at ICAS or "intermittent" duty ratings,
not continuous duty, unless you are planning to put a 15 watt unkeyed
carrier on the air and leave it there permanently (or until FCC and your
fellow Hams storm your front door). 

WARNING, WARNING, WARNING Will Robinson! (Remember "Lost in Space" or have I
dated myself yet again?) 

Do NOT put your K2 on top of or next to a power supply, especially a
"linear" power supply. The magnetic field around the power transformer will
invoke various gremlins in the K2. The K2 has been "hardened" against most
of these gremlins, but it's not absolutely problem-proof. The magnetic field
from the power transformer flopping about at 60 Hz gets into the toroids and
can cause various things from frequency warble on the signal to hum on the
carrier. 

Recommend keeping a small supply at least 6 to 12 inches away from your K2.
After discovering that my supply went on a stool under the operating desk,
freeing up space on the desk and keeping it a couple of feet from the rig.

Santa is loading up his sleigh with a K2!

Any recommendations on a 5A power supply that won't dwarf this and behave 
electrically?

I've got a 20A Astron that powers my current rig that I'd like to move to 
the lab.
