I for one would like to see Elecraft produce a power supply optimized for the K3 and matching Elecraft accessories. For years I owned a Kenwood PS-50 power supply and regretted selling it a few years ago. It was rock solid and absolutely quite and yet matched my TS850S. I currently own two Astron RS-35 power supplies, but they do not have the fit and finish of the Kenwood. Any yes, both of mine have a small but noticeable amount of hum. The Kenwood PS-50 fit in an enclosure that is just slightly larger than the P3. I am sure that Elecraft would ensure top notch rf filtering, light weight and with plenty of auxilliary outputs for running various Elecraft devices including the KRC2, P3 and KAT500.

OEM supplies - available in many quality levels, form factors and price points - are used by several other manufacturers as the core of their "matching" (or internal) power supply offerings. 73, ...
