It's a Rock

Time owned: more than 12 months

I've had mine since the mid 80's. Got it used at a hamfest. It stays on all the time and I've never had a bit of trouble with it. Using it to power the IC-718, the VHF/UHF dual bander, the stand alone 2 meter rig and all the 12vdc shack accesories. It runs into my PowerGate to run the shack and keep the backup batteries charged. I have to get close and listen very carefully to hear any hum. Not enough to worry about. If I ever need to replace it I will get another Astron. It's one of those things you just turn on and forget it's there.

Great supply! I wouldn't have any other supply for powering my 100W HF rigs and a few other items including a 2 meter rig, and LED lighting around my shack.
I had to do a simple replacement of the large filter cap (available from Digikey), but other than that, it's been trouble-free for about 16 years. The supply has been on more than it's been off during that time frame.
I can't say enough good things about this supply, it's based on the LM-723 regulator chip, which is pretty much the industry standard for higher current linear supplies.

Going on 13 years now - no problems!

I've been using my RS-35M for about 13 years now, switching it on and off at least every other day. Turning it on and off thousands of times all these years doesn't seem to be an issue. It powers ALL my rigs, small and large. I have not had one problem or issue with it. Mega high praises to Astron for manufacturing a 'bulletproof' and ultra reliable power supply!

I have been using an Astron RS35M for well over 15 years. It has been a solid, reliable performer for me.

I have 4 of these bad boys in service. 2 run my radios, one runs a repeater and the 4th one is used as a bench supply. All are over 15 years old, not one failure. Solid as a rock.

Ultra-Reliable

I bought mine used around the same time that I bought a pre-WARC Yaesu FT-107 around '79-'80. This is an early model that only has one meter with a switch. It's one of the very few pieces of equipment that there's never been a reason to replace or upgrade and has been my station supply ever since. In nearly 30 years of continuous,daily operation, I've never had a single problem with this supply. I ran it hard for years on RTTY in the early 80's without so much as a hiccup. Astron has a very dependable product in their linear supplies.

Returning this one!
|
Time owned: 0 to 3 months

Purchased this less than a week ago. No issues but have not put a full load on it either. What I found troubling was opening the top cover. The transformer looked like crap with wires that had been pulled out of the paper windings in the transformer. The paper was torn and bent, wires with the insulation melted from the person who was not careful where the hot soldering iron was while soldering. This looks to me like more junk from China. Sure is pretty on the outside but take a look at the insides.
Another issue is there are only TWO posts on the back for hooking rigs or accessories to especially if you have small RCA type phono plug wires it just doesn't work well. MFJ power supplies have little slot type places for these wires on their supplies. Calling HRO about this I was told I would need to spend another 75 bucks and buy the Anderson Power Pole strip. Hmmmm, they makes it around 260 bucks for this thing. Don't think so. This is going back and buying an MFJ.

I have been running my Astron 35M 24/7 since 1994. That's 15 years of absolutely trouble free service. What more can I say.

Well we live and we learn or so the saying goes, like a lot of hams I thought the Astron power supplies were the cats pajamas, all those years with no issues, well I had an issue and man did I ever learn a lot about Astron power supplies. Turns out most of the praise heaped upon Astrons is given by lucky hams, lucky enough to not have been bitten by some of the Astron problems. My problem with my 35amp metered power supply was a failed pass transistor, but while I was in there I made several mods to the unit, mainly replacing the dual rectifiers with one 50amp unit, and installing a cooling fan, along with 50% heavier pass transistors, NOW I have a nice power supply, 48 hours of RTTY and she's cool to the touch,
Anyone who thinks I am wrong on my negative comments needs to go to this web site and enlighten themselves, I can honestly say these guys helped me to rebuild this basket case into a truly heavy duty power supply, http://www.repeater-builder.com/astron/astron-index.html Excellent reading guys and gals!!
