Re: Ferroresonant Cnst V transfmer; Faults?
It probably has a paper resonating capacitor. And we all know what happens to paper capacitors, given enough time...
The value is fairly critical. Ferroresonant transformers work well, but they are critical as to supply frequency. So, thinking laterally, they'll be similarly critical as to capacitor value (given the frequency is correct). You may have to replace the capacitor with a biggish-but-slightly-too-small polypropylene AC-rated capacitor, with a few smaller ones in parallel to bring it up to the ideal value.
