Time owned: 0 to 3 months
Chinese and poor quality product firmed by Alinco. It is the same power supply like QJE.
Very loud and buzzing transformer.

Great supply  Time owned: more than 12 months
Had one for over 7 years. Lightning took it out. Ordered another one. Fan was bad. Sent it back. ALINCO is not making them anymore. They say they are on their site. But all the dealers say it has been discontinued.

Bought a MFJ 4035MV. Front looks like the same layout. Opened up (of course) and the inside is the SAME as the ALINCO, except it has a 2 prong plug instead of 3. Bob Heil would be happy.

Reliable and quiet  Time owned: more than 12 months
No problems/noise for 2 years, although its now my backup as upgraded to larger Astron unit. Not too large, very quiet.

Solved RFI Problem  Time owned: 0 to 3 months
I purchased this supply as a replacement for an MFJ-4245 switching power supply. The MFJ was causing interference to my garage door remotes. A linear power supply would not have that problem since they do not generate RF noise as switchers do. I set about to find a good one. I selected the Alinco DM-340MVT after researching reviews and specs. It was a bear locating a new one as they do not export to the USA anymore but I was able to find one by extensive search engine use.

The power supply works great! No RF interference or noise, excellent regulation, runs cool (unlike some cheap linears that run very hot) and very quiet. My only disappointment was that the meters were not illuminated. I did find a mod for that by AE1S ( I now have an illuminated Alinco DM-340MVT!

Been a solid performer for 14 years.  Time owned: more than 12 months
I got my DM340MV in January of 2000 and it has never failed me yet and runs quite. I would buy another Alinco if I needed one.

SECOND ONE SEEMS FINE SO FAR  Time owned: 0 to 3 months
I bought this supply based on its many features and the positive reviews on this site. I always but Astron but I was looking for flexible connecting features which Astron does not provide. Most of the reviews state that this unit is very quiet even with the fan on. That was one of my requirements. Ten minutes after I had it turned on without a radio connected, the fan went on which sounded like a weed trimmer! Whats worse is that the fan never turned off. I immediately returned the unit for another new one. This time all seem well. If I have problems with this unit, I will buy another Astron and use it with a Rigrunner. I give this a 4 because of my experience with the first unit. I will do a second review after 6 months which will hopefully be a trouble free experience.

Great Supply!  Time owned: more than 12 months
I've had mine for 12 years. It powers my entire station and it is solid as a rock! I leave it on most of the time and it has never given me ANY problems. Love the versatility with the voltage adjust, meters and cigr lighter output. I recommend it highly.

Broke after 2 Months  Time owned: 0 to 3 months
Love the power supply. Rock solid for near 2 months, then it dropped down to 11.8 volts at the center notch on the control knob and 13.5 at the far right position. Turned the supply off left it over night started up again 13.8 at the mid position. Was fine for a day and same thing happened again. Also Volt meter needle was oscillating back and forth and measured a .75 volt swing on a Fluke meter. Supply is of to GRE America on Monday for warranty repair.

Solid Unit  Time owned: more than 12 months
I've used my Alinco DM-340MVT for over 1.5 years. It's so quiet that I forget it's there. Solid construction, rugged and dependable. It powers my tuner, Flex 5000, Elecraft KPA-500 and my FT-857, and occassionally other gear. I'm so impressed with the quality that I ordered an Alinco switching power supply for my portable needs. What else can be said about a power supply that does exactly what it's adversited to do?

Rock Solid  Time owned: more than 12 months
As in the title!
Very quiet and rock steady operation, not causing any interference at all.
The only potential improvement would be a back lighted display but this is definitely not a deal breaker as in my case it was essentially set (the voltage)and forget.
The heat dissipated is quite noticeable in a small shack but this being said, the housing never gets any warmer than lukewarm. Would not hesitate to recommend this for a permanent installation.
