I found that site and referenced it above also.
The only way to find out is to try it Astroj guess. The schematic is really all you need. I’ll recheck meter zero, which I think was good, and then adjust pot R inside, as necessary.
Astron RSM Manual
Also checked negative side of DC output: August 14, Picked up a used RSM. As for illuminating the meter, that is a piece of cake. Dragging up an old topic. Not sure what, if any, problems I might see as a result and am inclined to leave it alone for now.
You can login to do that! But this means that the line-cord on the power supply is also acting as the safety bond for the device I will say computer, instead of radio.
The LEDs can be attached many ways, including a hot glue gun. April 26, There is no preview for this item! Icom America does answer their telephone for support calls.
The last I checked Astron website had schematics of all their linear power supplies. The Astron website appears to only have a catalog and no support information.
Looking for other manual? Not too much in there but you can never astrno too much info. Because the ground conductors are also of different gauges wire size the DC return current from the radio is now also going to be trying to share the connection through the earth ground system.
In addition, some files amnual archived, so you need WinZip or WinRar to open that files. If you have grounds on your radio equipment at other places like the antenna, tower, coax you are creating two earthing ground return paths of different capacity and with ever so slight differences in potential. This creates what is known as a “ground loop” that can introduce AC hum in to the DC supply ground return leg.
We’ll see you in a couple of weeks it’s that deep of a bench.
Astron VS-35M Variable DC Power Supply gets an upgraded MOSFET over-voltage circuit
Two white LEDs with a single dropping resistor is all that is needed. I had called Astron but they were not very helpful, only saying “it depends” and not offering any rationale. You could suffer a fatal electrical shock!

I switched it on and just checked unloaded voltage with my DVM As for manuals, I wasn’t aware they had one or why a person would need one.
Good luck to the repair! If you can’t find the schematic of the RSM, let me know. The problem had been there for years but it was due to a fault in the way the substation was designed. Repairing the Astron RSA http: If this is something like a radio or a piece of industrial process equipment where there are distributed connections to the earthing system then it can introduce problems. Maybe I need to try someone else there.
ASTRON RS35M Service Manual download, schematics, eeprom, repair info for electronics experts
Checked earth safety ground to chassis resistance: Please, do not make a copy of the downloaded manual and do not offer fs-35m sell it, just use personally to repair defective appliance! New to Ham Radio? July 28, However, I suggest you Google this for a more detailed and no doubt better way of doing this.
I also thought maybe my meter lights were burned out, as some have noted, but on further searching found that since my unit has aztron fixed power cord, it’s likely older and never had meter illumination. I’m thinking maybe the Astron should be set that way too if iCOM designed their “system” that way.
