Please, do not make a copy of the downloaded manual and do not offer to sell it, just use personally to repair defective appliance! For some new radio amateurs English is a second language, and can adtron understand some electronics concepts and repairs via video YouTube instruction or pictorial diagrams.

Looking for other manual? The only way to find out is to try it I guess. On further searching, I found a wealth of info here: Had a typo above corrected in red.

It ended up being in one manuap conductor that was not bonded correctly,it was a MCM cable that had 6 volts at amps running through it. It appears you have a handle on operating the unit, even to the point of correcting meter errors.

If you rs35m not familiar with electronics, do not attempt to repair! I cannot find anyhting on Astron’s website, except their catalog. Now Manua hoping that older units were built better and this one will last me a good long while. Anyone have a copy or know where I could obtain it? However, I suggest you Google this for a more detailed and no doubt better way of doing this.

Two white LEDs with a single dropping resistor is all that is needed. Dragging up an old topic. I’ll recheck meter zero, which I think was good, and then adjust manjal R inside, as necessary.

May 18, I had called Astron but they were not very helpful, only saying “it depends” and not offering any rationale. But this means that the line-cord on the power supply is also acting as the safety bond for the device I rs-35k say computer, instead of radio.


Is this the correct site? 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 manuak system. Astron sent me a manual in e-mail.

Icom America does answer their telephone for support calls. Checked earth safety ground to chassis resistance: April 27, New to Ham Radio?

Astron VS-35M Variable DC Power Supply gets an upgraded MOSFET over-voltage circuit

Usually this would be much more pronounced on instrumentation loops industrial control with pressure transmitters operating off of a mA current loop for example.

Picked up a used RSM. The last I checked Astron website had schematics of all their linear power supplies. I’m thinking maybe the Astron should be set that way too if mwnual designed their “system” that way.

You can login to do that! I switched it on and just checked unloaded voltage rs-35 my DVM July 30, ,
