[Elecraft] K4 Power Supply Recommendation

[John Shingara]

Thanks everyone for the replies and advice; much appreciated.  This is exactly the kind of question I would bring to my SK father so it was very nice to read the advice posted as if it were coming from dad.  It was all practical interesting. It made me miss having these discussions in his shack while he was building some project.  

I have since ordered an Astron RS-70M-AP.   It’s a big old (48 lb) linear and more than I will probably ever need.  The 70 was only $10 more than the 50 on HRO and it has a cooling fan where the 50 does not so I thought it may be more robust.   I plan to run all of my HF from this amp (KX3, KX2, and hopefully soon a K4).  I’ll use the PowerWerx SS30DV switcher for my Yaesu FTM-400DR VHF and UHF in he shack.  

Thanks again everyone!

I was planning on buying another for the K4 but thought I would ask opinions first.  I am assembling my first real HF station and going the cry once route.  I would rather pay a bit more up front and get something solid rather than saving a few bucks now only to upgrade later.

My budget is let’s say $500 and my question is would buying a bigger switching or linear PS for the K4 make sense?  My KX3 PS has caused me no issues and if that is the way to go I am groovy.
