I currently use an Astron RS-35M in my home shack. Yes it's big and hot but
it works well, puts out no RF hash and is easy to repair if something goes
wrong with it. I also have an MFJ-4125 switcher for backup that I've had
for years and it works great with no RF hash. It does have a noisy fan
on the fan wires. Problem
solved. I like the supply because of it's small size and light weight. I use
it when portable.

I have 2 of the SS-30M and have never seen this problem (fan noise).
They are very quiet whether the fan is running or not. I like the M
version with meters. They are powering 3 radios including the K-3 and 2
brick amps. I find it helpful to have the ammeters. For example, this
past weekend I

Maybe a component in your Astron is aging. I have a 70A Astron that's over
20 years old and it's slightly warm, but that's it.

Samlex 1235, maybe any 12xx. Using 1235 here: No spurs, no hash, no
noise, just reliable to 35A. I also hear the Powerwerx is good
through I've not tried it (yet).

The switchers were fairly RF-quiet at low current draw, and then
created more noise as they drew more current. This is fine for

It stays on floor in battery case with 10A circuit breaker in series at
