Hello I have A Astron RS-70A power supply. The output Volts is currently 13.8Volts. Is there a pot somewhere inside the power supply to adjust the voltage output? I would like to get 15volts out.

Thanks

No body answered but this is what I found. I got home. Unplugged the power supply, took the top off, found A printed circuit board connected to the capacitors. I had to discharge the caps and remove the board from the cap. buy removing two screws. I was able see A thumbwheel. I adjust the thumb wheel got the volts up to 14.5 volts out. I am happy.
Hope this helps anyone out there that might want to adjust the volts on their Astron power supply.

Thanks

AFTER you unplug the power supply... Simply short across the two terminals on each capacitor.

I recently repaired a RS-35A, I believe they use the same board. I was able to set the voltage without removing the board using my finger and a voltmeter connected to the output.......
