Hello all, my GME PSA 1225 power supply (25amp @13.8v) has suffered a bit of a voltage drop down to around 12.2v and falling under 12 when TXing. This is ruining my TX on my Kenwood TS 680 at present. Is there anything I can do to adjust something inside to bring the voltage back up?

Where and what is the power supply plug being used at and what else do you have on the ac plug beside the power supply? If you have as some may do a portable heater, air conditioner and or anything else that may be taking away from the ac current you might have a drop at the plug on the ac. If that may not be the problem it could be possible the problem is in the power supply itself and may need some repair. Just a guess on my part and you might want to ask one of the TECH"S on this one. I hope I have been some help. Have a nice Thanksgiving and a Merry Christmas |

A few tenths of a volt when drawing at or near the supply's capability isn't unusual.
Also, a Kenwood will run just fine on 12 volts. In fact, it should run just fine clear down to 11 volts. I run mine on 12.0 volts to increase longevity of the internal components.
To answer your question directly, there may be an adjustment inside the supply (assuming it's regulated) to change the output voltage.
