- Replacing Electrolytics with NOS parts - 4 Updates
| Dan Green <dhg99908@hotmail.se>: Aug 28 12:29PM +0100 Hi all, Is this okay? I'm talking about replacing electros that have been in service for like 30+ years and which have a rep for failing by then (Frako caps) with old but unused electrolytics; so called "new old stock" caps of reputable manufacturers of the same spec. I can't see an issue with this but am no expert so.... what d'yall think? Dan. |

I was fooled once by an old Leo3 computer power supply unit that had four 500uF electrolytics in parallel. It smoothed well until the last one failed. |

It has been my experience that electrolytic caps of a certain age are as likely to fail just sitting on a shelf as in service. I suggest you purchase modern, fresh caps of the proper size, voltage and style from a reputable source made by a reputable manufacturer. Why risk it? Peter Wieck Melrose Park, PA |

Personally I've not had any problems with NOS electrolytics provided they were sourced through RS or suchlike originally. But YMMV. |
