Adjusting a Magnatec 950 converter
I have an old Magnatec 950 converter that is slowly losing its charging voltage. 11 years ago it used to charge at 13.6v or so and is now down to 13 v. can these old converters be adjusted? Manual say...

Thanks Chris, I was hoping there was some kind of pot inside to adjust.
Ferroresonant converters have the output voltage set by physical design, not by adjustment of a feedback circuit. It's a similar basic concept to what some inexpensive generators use for their voltage regulation.
If you varied the input AC power frequency, you could adjust the output voltage rather handily. Your electric utility would probably not appreciate such tinkering.
