[Elecraft] Power Supply For K3?

[Buck - k4ia]

35A Astron linear running for 24/7 10 years at home with no issues.

Samlex 1223 switcher at Field Day for 24 hours of constant CW in 
Virginia-summer heat with no issues.  There is no "head room" in this 
supply to run any other accessories so it is a bare minimum for 
capacity.  I do not hear any RFI with it but I only operate 40M.  I 
understand Samlex supplies are quiet but, as others have pointed out, 
there is bound to be noise somewhere.
