I have a Astron RS-35A power supply. Does anyone know how to turn the voltage up? I would like to turn it up to 14.0 volts. |

The regulator board is mounted on top of the filter capacitor by 2 screws "parts side down". there is an adjustment pot (Only one on the board) you can reach with your finger.......
BUT the big question is why would you want to fool with it for an additional .2 volts??.....

Because I feel 14.0 is better than 13.5. Which I see a 13.4-5 when powering up radio. |

Be advised that 14.0 volts might be a tad too much for some radio components, particularly IC's.
I usually turn my power supplies DOWN to 12.0 volts to match the rated voltage for most of the internal components. I have some radios made in the 1970's that still work perfectly.

Ok, Thanks Funtime, and Tech833. I'll leave it as is. |

A little research on your own will disprove that in many cases.
Look up some of the ICs in your radio online. Read their rated and maximum voltages.
The ICs that run directly from the radio voltage input (not fed from a regulator) are the important ones. You'll find none of them rated at 13.8 volts.
13.8 volts is a flooded battery float voltage. Yes, you can also run 12 volt DC appliances from 13.8 VDC, but it won't provide the greatest lifespan for the devices.
Lots of "techs" suggest "volting" your radio for more power output etc. That means, running it on more than 12 volts DC. You can indeed achieve more power, at the expense of reliability and long life of the radio. Your choice, of course.
