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.

Subject: [RFI] New Astron Switching PS RFI?
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.
