    The club I was in had an RS-35M, and it always worked nicely. I just bought one to replace an MFJ-4035MV. I can say don't buy the MFJ. In MFJ's defense, they didn't design it and only stuck their name on it (mine has an MFJ sticker stuck on the front), but I had problems with it picking up RFI and shutting down the cooling fan. When I took a look inside, it looks like it was homebuilt. Lots of little baby boards scattered around, with poor solder joints and poorly stripped wires tacked here and there. The filter caps in it were just a bunch of cheap electrolytics wired together. The Astron is much better built. Big electrolytic with large screw terminals on it, one single PCB with all the parts neatly soldered to it, and it doesn't pick up RFI. Oh, and the MFJ only has a two conductor line cord, and the case is floating. Could be why it picked up RFI so well. The Astron uses a computer style line cord connector, and the case is grounded.

    I have an RS-50A and it has never been turned off since the day I acquired it, no problems with it. IDK how old it is but it was given to me by a local repeater owner who used it to power his system for quite some time.

    No prob, glad you got some use out of 'em :)

    I'm guessing you still had the urge to pop the case anyway ;) If nothing else to check for conductive bits floating around etc......

    I was thinking about doing the same mod so I can run my tuner meter lamp and other doo-dads.....

    Looking at the punch-out size makes me wonder if there isn't a power pole made that snaps directly into the spare cutouts ? I'm hesitant to do all of the shimming and zip-tying and such, would prefer a snap-in. Must not be a standard size or anderson would make it.

    Astron has had proven peformance for me and has never cost me anything for repair. I wouldnt hesitate to buy another one. It will give you years of trouble free service.
