Bush TV22 / TV24 mains electrolytic capacitor - reforming a NOS find

[Helder Crespo]

Hi
I got an exact replacement for the dual mains cap in the TV22 / TV24 (and possibly other makes and models too) off eBay. It's a NOS Dubillier made in 1975.
I built the dual-voltage reformer described elsewhere on this forum, and tested it today. The capacitors reformed beautifully. After 15-20 minutes on the reformer, I got a few tens of microamps on each section, so basically like a good new capacitor. Some pics below (reformer and cap). Right now, there are two more of these caps on eBay from the same seller, in case anyone is interested. If they behave as well as mine, I think they can be a great replacement. If you have a reformer around, the process is cleaner and less time consuming than prying open and restuffing the can of the original cap. As for long-term behaviour, I can't tell yet, but the extremely low leakage current appears promising.
