Contributing to the Astron fan mail… My main shack PS is Astron RS-50M with two RS-35M in backup. I originally had just the two RS-35M supplies but just had to move on up.
Never a problem with any of them although the RS-35M supplies are not actively being used at this time. 73, phil, K7PEH > On Apr 17, 2020, at 1:52 PM, Lyn Norstad <[email protected]> wrote: > > Currently (no pun intended) I am using an Astron VS35M which gives me a > linear, fully variable (both voltage and max current) metered supply.
