Imo, linear power supplies are still the best. Case in point, my Astron RS-35m has not missed a beat, it was the first purchase I made when I passed the technician(c) exam in 1968.
To this day, it continues to power all of my 12 to 13.8v needs.

Nuff said here about that.

I had the SS-30 (no meters) in the '90s.   No formal testing, just 
observations.   It was RF quiet, I mostly used it on VHF but at least once on 
HF.  It had a regulation problem if RF was in the shack, such as a nearby 2m 
mag mount in a hotel room on a marginal ground plane.  The RF/regulation 
problem went away when I bolted my 2m rig bracket to the top of the PS case.

The PS lasted about 15-20 years.  There was no collateral damage to my rig when 
it died.

All:

Has anyone tested the latest Astron switching power supplies for noise?
I read a few reviews that said the new units produce no noise on HF.
