Works well but . . .  Time owned: 0 to 3 months
the fabrication Quality is low: The Voltage adjustment Knob is shaky, it easily moves up and down when touching it with a Finger slightly and then the Knob touches the Cabinet when turning it, totaly ANOYING !
My 100 Watt HF Transceiver takes ~17 Amps max. according to the GSV-3000 Scale, yet when I transmit with 100 Watts, the LED Light is going darker when I am speaking, as if the Power Supply was running out of Power but actually there is more Power than needed for a 100 Watt HF Transceiver. My GSV-3000 has a CE Certificate and is limited to 25 Amp, Serial Number is 905****5.

This is a good product (4) but not great (5). The lower fabrication Quality i described earlier makes me rate it 4, else I would rate it 5. There is no Problem such as strange Noises, fluctuating Voltage etc. The Fan is quiet, quieter than the Fan in my Icom IC-746 Transceiver but not as quiet as the Acom 1000 Amplifier.
I payed 120 Euro (new), that's about 160 US Dollar, for such a Price I CAN expect better but after all it is a solid Power Source.

You connect it and forget it!  Time owned: more than 12 months
I have now used the GSV3000 for almost 2 years. A few months after my first review (March 2007) I bought a new IC-756PROIII HF transceiver and about six months later a new IC-910H VHF/UHF transceiver. Both are connected to the GSV3000 with various accessories.

After extensive use, I am in full agreement with other reviewers who say: " simply connect it and forget it". That is so true. I recommend this power supply to all hams.

Nevertheless, going back to my first review, it still bothers me that Diamond made the feet too small in my opinion...

73 de TF2JB.

Widely used, & one of the best PSU around.  Time owned: more than 12 months
I have been using the Diamond GSV-3000 PSU for several years now. It has been working trouble free with my FT-920 rig, & several vhf / uhf transceivers connected to it. Recently I bought a new FT-450AT, & had it connected up with another 25amp ( Not Diamond )PSU. This PSU has now developed a fault which I thought I had dealt with in the past but the fault returned again, so I have decided to give up, & purchase another new PSU. With no doubt, I will be going for another Diamond GSV-3000 Linear PSU.
I thought of going for a switch mode PSU, which are much lighter, & easier to fit in any shack rack, or shelf, but having had a trouble free PSU like the Diamond GSV-3000 for several years, I will with no doubt head for one the same, which I know it will give me many pleasurable hours on radio, as the other GSV-3000 still in use with my other radios.
This is a work horse !!!
Well done Diamond, & I hope they don't do away with linear, & heavy PSU, they will last a life time.

Just sits there doing it's thing.  Time owned: 6 to 12 months
I bought one last year to replace a very old 20 Amp. unit. Turn it on, set the voltage, forget it. I use it to simultaneously power the K2, the FRG-100 and various accessories; no more wallwarts, they ALL radiate at some frequency.

Very good linear Power Supply  Time owned: more than 12 months

For a couple years I use two of the Diamond GSV-3000 linear Power Supplies for my 12 Volt transceivers.

Excellent performance, very quiet and smooth operation, no heat or noise what so ever. Highly recommended for the price!

Good Value  Time owned: more than 12 months
If you need 50-60 amps at up to 15 VDC, connect two GSV-3000 in parallel.

You should use a 0.1 Ohm resistor in series with each +ve line and the other ends common and connected to the load.

This prevents one supply from grabbing all the load.

Resistors can be made by winding 30-35 feet of 14 awg copper wire on an air former, a bit like an HF coil.

Excellent power supply  Time owned: 0 to 3 months
After considerable research I purchased the GSV-3000. It cost me about USD 190 (including all costs) to this country. This unit is the European CE-version which means that it is limited to 25A of current which is sufficient for my needs. Yes, it is heavy; about 9,5 kgs but it is worth it. In that respect I am referring to the problems I have read other hams have experienced with some switch-mode power supplies. Having now used it for about a month with an FT-840 transceiver, I can state that I am 100% pleased with the GSV-3000's performance. Rock steady voltage and the internal fan is wonderfully quiet. I never even notice that it has one. On the other hand, the FT-840 certainly has one... The supply also has 2 outlets for other use (up to 6 Ampers) which is a nice touch since one can connect accessories and even a 2 meter transceiver. I was not sure about the cigarette lighter socket that is also provided (up to 10 ampers), but since it is covered with a rubber cap when not used, it does not bother me... The metering provided for voltage and current are also a nice touch. And if you want to go below or beyond the usual 13.8 VDC, voltage can be varied from 5-15VDC. The built quality is excellent. I was pleased with what I saw when I looked inside (I have built many power supplies myslef). And the colour of the unit blends well with other equipment in my shack. The only thing I miss is that there are no lights behind the analogue meters, but I might add those myself in future. Also, Diamond might make the feet a little bit larger. All in all, I can recommend this quality power supply to all hams.

Buy and forget;)  Time owned: 6 to 12 months
Well, I bought this Power Supply to handle my TS-2000 and to be honest I've forgotten I have power supply;) Great device and even nice enough that my YL doesn't cry if it is on the desk not below the desk;)

Strong and quiet  Time owned: 3 to 6 months
I bought the GSV-3000 to replace a physically much smaller switching power supply. The switcher caused a lot of noise on 80 m and below. The Diamond GSV-3000 is technically just like the Yaesu FP-1030 A, only that the Yaesu has a steady 13.8 V while the Diamond can be adjusted between 1 and 15 Volts. Of course, it is quite big and heavy, it would be nice to have the DC outputs on the back or to have some illumination for the analog gauges, and yet, the power supply can't be beat: It is rugged, no interference on the low bands, there is very, very little transformer hum, the fan is quiet and efficient and hardly ever running. I got mine for an incredible 111 EUR.

Long Term Reliability  Time owned: more than 12 months
I bought my GSV-3000 in Hong Kong the summer of 1996. It is the only external dc supply which I have at my Hong Kong qth and the only one that I need. It has seen several generations of radios come and go over that period ranging (in terms of dc current draw) from a FT-817 to a TS-480HX. Its performance has been flawlessly reliable and it behaves like an invisible unit. It even worked satisfactorily to power the 480HX to 200 watts pep output even though the 480HX draws 40A intermittent service (with both dc cords connected to the same terminals on the supply). It is very heavy indeed. It has also dwarfed some of the radios that it has powered in terms of size and weight. It is currently back in its box as I am currently using a IC-781 but I am confident that it will perform as expected whenever it comes back into active service.
