[Elecraft] OT: Linear Power Supply Manson EP-925/EPA-9300 or Diamond GSV-3000?

[Thomas Martin]

Hello,
thinking about buying a (non-sitched) supply
I ended with several alternatives:

Manson EP-925 or EPA-9300 (seems to be 
        some kind of a newer version of the EP-925)

or the Diamond GSV-3000

All of these are DC-regulated and will supply abt. 25Amp 
at 13,8V and may be regulated from 1 or 3Volt to abt. 15V.

(The price here in Europe is at abt. 150Euro/180USD for 
these supplies)

Perhaps someone around here has some experiences with 
these supplies especially concernig their usability for RF
equipment, stability, protection, noise, hum/shielding and 
fan noise.

As far as I know a modified (fixed output voltage) version 
of the Diamond GSV-3000 is distributed from YAESU as 
supply (FP-1030 ?) for some of their transceivers what 
might vote for this one (RF-usability) but the Manson 
"looks" a bit more "trustworthy" in my eyes.

Did (so far) not manage to get an in-depth datasheet of 
the GSV-3000 to do some comparison myself.
