[Elecraft] Astron 25 amp supply

[Hector Padron]

My two cents,this might be a good choice for you,for about 4 years I have been using an Alinco DM-340MV  35A  analog power supply to feed all the radios I have owned before,IC-756ProIII,FT-950,FT-2000 and now the K3,its very stable,even taking out 25A continuos the drop of voltage from 13.8 at the output is just 0.2V and the ripple is no more than 100 mV on the scope,it has two meters,one for voltage and one for amperes,good looking,black color to match the radio,I payed around $175,I think its a good choice for the K3 and its no switching,so it will not generate any "birdies" on any band,good luck with your search,73

I've been using an Astron SS-30M switcher with my K3 for a while now 
and previously used it with an Icom 746 for 7 years with no problem. 
The SS-30M is rated by Astron at 25 Amps continuous and 30A "ICS". 
The "ICS" rating should not be confused with the widely accepted 
"ICAS" (Intermittent Commercial and Amateur Service) rating that has 
been around for years. ICS is an Astron invention that purports to 
represent a typical duty cycle for ham use and allows them to claim 
higher current capability than the supply would have in truly heavy 
duty service. I would not recommend using any Astron supply rated at 
less than 25A ICS for a 100W HF radio. That being said, the SS-30 has 
performed flawlessly for me for a long time, and there are thousands 
of them out there that seem to be working equally well.
