Great powersupply
|
Time owned: 0 to 3 months
|
Really good powersupply except for the noise from
the original fan (a very cheap fan)
I changed it with a noiseless PAPST fan and it is
a different experience now.

Excellent Supply
|
Time owned: more than 12 months
|
|
I've had this supply over 2 years and have never noticed any RF hash or birdies. About a year ago I started using it on the ALS-500M Linear which runs it right to the limits (I do back the power down a bit but right to the output limits of the supply), and have never had any problem with it. This supply is quiet and bulletproof!

Nice pice of electronic
|
Time owned: 3 to 6 months

Tho i was recomended that i wouldnt by an switched PSU becouse they tend to "leak" out on the bands ,
But i must say i´m active on 3.5-29mhz and vhf/uhf and havent heard anyone mention that they hear any rf "leaked" by the PSU , my ham equipment tend to be in a narrow space psu,amplifier,rigg,tuner, all fits on 1m of table , i cant say that the FAN is disturbing at all , my pc generates many times more noice than the psu
Curently i power my
FT-897
V-ULA 50 100w vhf/uhf Amp.
gotta say im more than pleased with the PSU , if i ever need another one i wouldnt hesitate to buy me
a second one :)

Great PS!

I had one of these power supplies recently and highly recommend it. It will handle any HF rig you throw at it without even working. I was using it to run a FT100D with a 160 watt amp, and it did both just fine. Never even broke a sweat.
More importantly, I didn't notice any noise or hash coming from it.
The front panel cigarette lighter socket and light duty clips are great for hooking up accessories. The meter seemed pretty accurate; cant comment on the built in speaker, but it is a great idea.
Also, this PS just looks classy sitting on your desk or workbench. You can tell it is a well made supply.

Superb
|
Time owned: more than 12 months
|
Have this PSU for about 2 years now, and not a single complain. Well, like other reviewers, the fan is a bit noisy, but comparing with my PC, don't know who wins the prize...
This unit is only used at the moment to suply my IC-746, and sometime my celular phone with the car kit hi hi. The needle never went over the 20 amps.
Had purchased this for it's dimensions, weight and appereance.
Had to wait a little bit to buy it, but am very happy with.

It's okay...

It works fine. Fan is a little noisy. Ammeter worked intermittently right out of the box (needs a tap every so often). Light bulb burnt out in 6 months (incandescent?). Sending it back to get meter fixed while still under warranty. No noticeable rf hash problem yet (too much noise from other sources to tell).

Switched Mode PSU
|
Time owned: more than 12 months
|
|
Had one of these units for just short of two years, was a bit dubious about buying given that it was switched mode, but the output was very clean with the naturally generated RF hash being superbly filtered not being evident on any band or rig which I qwned at that time. Worked well being stable and smooth, but the fan got me in the end being just a tad too noisy for my liking. It eventually blew the guts out of an I.C. due I think to overheating and possible underating. Overall I would recommend it as a good quality unit better suited to those who are hard of hearing, the efficent fan is a total pain.

Excellent
|
Time owned: more than 12 months
|
I have owned both of my GZV4000s for over one year, one is over two years old. I have two becaise of my needs for high current 12V and not because of any failings in the PSU. The fan is a little noisy, but its voltage stability under dynamic load is excellent, and you can pick it up without a hernia, another plus.
Highly recommended.

Nothing but PS!!

Fantasic power supply! I hear no discernible noise as a result of this supply. Sure, there's noise out there......powerline, blender in the kitchen, neighbor's vaccuum cleaner, etc.....but none from this supply that my TS2000 is picking up. The supply sits about 2.5-3ft away from my rig.
I would venture to guess that computer case power supplies and modern CRT monitors generate more noise than this supply does. I'm sure Diamond's manufacturer knew to design appropriate filtering for radio use into this power supply, whereas Sony or Viewsonic or NEC or whomever could care less about us RF weenies.
73 and happy holidays!
