HP 25 Power supply Self build


I've just got a mint HP25 with a rebuilt nicad battery - works fine. However, I know need to charge it and don't have a UK/Euro charger - does anyone have any ideas for an alternative connector I can use (easily get hold of) and connect to a cheap 10v transformer supply ?


I have a european charger for the HP-25 in perfect operating condition. Make an offer?


I have a 220/110V charger for a HP-21. Since the HP-21 is long gone, I don't need it anymore. That means, if the shipping costs form Germany to your location are not too high, I can give it away for free.

Anyway, have fun with your calc! Klaus
