[Elecraft] 25A power supply question

[EricJ]

Very happy with my Powerwerx SPS-30DM. Small, quiet fan when it comes 
on, RF-clean. I power a K2/100 and K2/10, plus a few station accessories.

Also recommend Powerwerx for Anderson Power Poles and accessories. Very 
nice company to do business with.
