Great video. I prefer the linear supplies as they are more repairable by the ham end user. In the past I had an Astron linear supply fail and I called the factory and they helped me troubleshoot my unit. Turned out to be a failed bridge rectifier. After that it was an easy fix on my part. I have used Astron supplies since the early 1980's. They support their products.
I have several Astron power supplies. I have a RS-50M I purchased new from the Portland HRO store in 1990, it has been in continuous use ever since. I have not had a single failure or the supply showing any signs that the caps may need replacing.
Thanks for the tour...been a customer since the old Burlingame "train station" store in the late 60's! Where are the Astron switching power supplies manufactured? 73 - Dino KL0S
I have several and they all around 20 years old or older. RS70-M RS-50A and more. I have fixed a few over the years and just basic problems . like solder joint break on buss bar on 50 and 70 amp ones . Just the weight and moving them around can have that happen. And power surge problem from mains. Usually the MOV inside burns up takes out fuse . And broken fuse holders. Be careful with the big ones. Sometimes a 723 reg ic goes bad. usually from a line surge. or poor grounding. RF getting into shack and supply. and with the linear supplies the pass transistors have postave voltage on them. Watch hitting outher metal . I just has a RS 35M come in for repair. The coax fell off dest onto heatsink and sparked onto the 2N3771 transistor blowing the fuse and the rectifier inside. Also I had to replace transistor because a hole was blown threw when it arcked over. it tested good but had a hole blown threw the case. They make 3D printed covers for them. printables and outher have the 3D files . I have a repeater cite with a 50 amp Astron supply with battery hook up built in. 20 years running. never failed. Has AGM telcomm 100 AH batteries (3) . The battery only last about 3 years or so. 200 watt VHF and UHF linked system on that supply . Astron is great stuff made in USA and they have parts if you need them . The 240V model will run 50 and 60 HZ . Used all over the world ! HRO is best place to buy them . great factory tour ! 73
I have 3 astron supply Fred repair one of my supply I going have Fred go thru my old astron 35 amp have him install new parts replaced the capacitor because they are old kc6nfv
I called Astron about an Out of Warranty power supply....we talked, they sent me two power transistors which I installed but it didn't fix the problem.....so I sent it in and they needed to replace something else and they didn't charge me for repairs or shipping back....Who does that....

What a Cool American Made Power Supply!
Have an Astron RS-50M,, RS-50A, RM-35M, and numerous RS-12 units. Thanks for the interview!

Very good power supply’s

nice that Kevin Bacon gave you the shop tour of Astron.
What's a Molex machine used for?

Hp switchers ,100 amps, automatic 110 or 220, and are load sharing
Amazing video AB9EW
I know what I will be buying from now on.

I'm sure the Porsches sitting around are good for employee moral.

Get them now because once trumps tariffs go into effect, they will be so expensive that no one will be able to afford them.
