I have a Sharp MD-DR470H Minidisc player with a gumstick battery, i cannot find a charger anywhere, can you please help.

I've deliberately avoided answering your question for a few days to see whether someone else had located a gumstick battery charger, but clearly they have drawn a blank as well. They were never a common item even when Sony sold them new.

You may wish to do as I do: I use broken MD players as chargers. There are millions of MD units lying unused, most are worthless now and many are broken (typically the fatal TOC error). As a result it's easy to get them for nothing on local FreeCycle and Freegle groups and often they come with spare discs, batteries and other accessories. best of all, most of them are still in working order so you may even end up with a free upgrade. Every bit of MD gear I own has come from FreeCycle and Freegle except for my superb MZ-n910 which remains in regular use.

As luck would have it, I was about to hit the "Post Solution" button when I found this one on eBay. It wasn't there when I last looked! it will hold two gumstick batteries.

I hope that my answer has been of use, please take a moment to rate my reply.
