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.

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.

Great power supply Time Owned: 0 to 3 months.
I just bought new GSV-3000 power supply.No RF hash or birdies.Automatic fan is good,no disturbing.It´s similar like Yaesu´s own FP-1030.I using it whit FT-897D and it works fine.It´s a well made "tank".
