RS 20 after about 25 years or so
|
Time owned: more than 12 months
|

I think I bought my RS 20 back in 1985 or so. Still working fine after many, many hours of operation.

Shack Workhorses!

Time owned: more than 12 months

I own two RS-35M supplies. One was mine since new and I pulled it out of the box. It is at least 20 years old and still completely stock. No failures at all. I open it once a year to vacuum it out and adjust the meters if needed.
The second RS-35M came from that auction site. Unfortunately the seller stuffed it in a postal service flat-rate box with a small sheet of bubble-wrap and called it good. It wasn't. Bent up chassis and broken meters but otherwise, it was electrically sound. I straightened the chassis as best I could, added some new meters (Thanks, Astron) and touch-up paint and this RS-35M is as good as the other one. I've owned it about 6 years now and it has worked flawlessly! Astron stuff is very rugged and very recommended.
For me, it's personal. I'm not big on switch-mode supplies for high-current transmitters. Probably not a thing wrong with using them, I'm just a purist when it comes to linear power supplies and transmitters. There's only one choice for my high-current needs, and that's Astron. I've simply found nothing better unless it's home-brewed with extreme care. I'm not that good.

The Best
|
Time owned: more than 12 months

I own several Astron power supplies. I wouldn't buy any other type.
All between the age of 1 and 20 years old, and they all work like the day they were purchased. A fine company!

Great!

These are great power supplies, all around. They put out great power, and last a long time. I bought one used, and it has never given me one bit of trouble. It has stayed on for years now and has survived many hurricaned too and still keeps on ticking.

Own many Astrons

Time owned: more than 12 months

I have 3 Astron Power supplies 20A, 35A and 70A. The 20 and 70 are about 10 years old and the 35 is about 5 years old. Never a problem with them that I didn't cause. I did pull too much from the 20A once and blew the bridge rectifier. A few $ and 20 minutes and I was back in business. Last year I broke the volt meter on the 70A. I called for a replacement which was to be paid COD. After two weeks it did not arrive. Astron then sent me one for free. I think the Customer Service was very good!

Good supply, bad after sales support
|
Time owned: 0 to 3 months
|
I purchased a new 25Amp switching supply based on the reviews on this site. I would say that I am happy with the electrical performance of the unit, but the second time that I used the rear mounted cable clamps the screw broke inside the connector, making it useless.
The store that I purchased the supply from will not take units back after 10 days and this hapenned within the first month.
I sent an email to Astron and also a letter explaining the problem, and it would be silly for us to pay $20 postage for a part that must only cost a couple of bucks. I can fit the replacement screw or connector myself.
Have I heard anything, NO. They could not even be bothered to reply to my email, and how much effort does that take.
I know that people slate MFJ, but their customer service is fantastic. I wish i had brought one of their supplies.
Do not buy one of these supplies and expect after sales support.

Solid PS/Well Built
|
Time owned: more than 12 months
|
|
I have had 5 Astron power supplies of either the 20 amp model or the 35 amp model. One is a 20 variable and 2-35 amp models I currently run. I have NO complaints of all the Astrons I have owned and have used them very much with NO problems. One thing I would recommend to people who don't need the variable is not to buy one for general use as the adjustment knobs can get bumped. These are some of the most well built, American made PS I have seen or used. Good price too for what you get.

Excellent Power Supply
|
Time owned: 0 to 3 months
|
I recently purchased a Samlex 1223 and kept it for around for 1 week before returning it because of RF hash problems.I am now using an Astron SS-25 and the difference is like night and day,especially on 10 meters.I do not find the fan noise objectionable simply because it just does'nt run that often and when it does it's only for a minute or two.Besides,with all of the other fans running on the computer,linear,and HF rig,it's no big thing! As far as the connections for the DC out,there is a VERY SIMPLE solution that everyone seems to be missing. My connections to the supply involve 4 wires,2 on the negative and 2 on the positive side.I simply used a 1 inch long #6 screw with washers and a lock washer on each and just put them into their respective binding posts and tighten the set screw on the side,END OF PROBLEM! Astron also includes an internal EMI filter,something not found on most of the others. With the Samlex,I had to play around with snap on RF filters on the power cord to reduce the RF hash on 75.
This power supply,and the others in the other in the Astron line are the only way to go when using a switching supply.

Solid, dependable RS-12
|
Time owned: more than 12 months
|
I've owned my RS-12 for over 20 years. In that time it has variously powered my TenTec Argosy & Icom IC-735 (50 W. setting), numerous VHF radios and has even been used as a battery charger for a car. I had the top cover off only once, to do a visual inspection and voltage check of the supply when I purchased it.
The supply puts out a solid 13.8 V. with negligible "sag" within the 12A. current rating.
