I help volunteer at a HS theater. They currently use the Telex intercom system powered by a PS-1F . They are running 5 BP-1002 beltpack units and have been for 10 years. This week they could barely hear each other through the system but could hear themselves clearly in their own headset. I've checked for shorts and open circuits at each connector box and check each connecting cable but don't find any problem. I'm showing at least 24v at the power supply itself. I eliminated the house wiring by connecting a beltpack directly to the power supply and daisy chained another unit to the first, still could not clearly hear the other unit. The only common item is the power supply. Could this be failing under load from all units connected. Just trying to be sure before replacing a $400 power supply. Thanks for any suggestions.

Thanks, I''l look into repair, may not be in time for my production opening next Wednesday.
The Telex PS-1F has no settings that I know of 1 common and 2 - 24v outputs.
Sorry, It has been a long day, I was thinking of the rackmount version.
Been there.
Didn't think like that, I'll check.
And, measure the DC voltage with a few beltpacks connected, with someone talking. If it sags badly under load, that would be a good clue.
Just from seeing the schematic, I would replace C1. As I've posted many times before, electrolytic capacitors frequently fail from heat and age, especially in DC filtering duties. That's an easy, $2 part to find. Just mind the polarity when soldering in the new one.
