Subject: i knew better but......
From: Brendan Hack (bendy_at_bendys.com)
Date: 2004-04-06

I just managed to blow the charging circuit on my original model recorder (20gig). The tip on the charger I've always used somehow got turned around so it was supplying a -ve center instead of +ve. This is despite the fact that the tip is securely taped it's connector specifically to prevent this from occuring. So it's time to get myself a new charging IC and decide whether my soldering skills are up to scratch or find someone with the necessary skills. If only I still worked at the Engineering Department at VUT, plenty of people there to help me out...

>From a previous email from Jörg I understand that I need an MC34063A to replace the existing chip on the back of the main board (which seems to be the one labelled 34063A in the bottom right of http://rockbox.haxx.se/internals/rec_iface_bottom.jpg, though I couldn't seem to find this chip on the schematic at http://rockbox.haxx.se/schematics/rec_main.pdf). I'd just like to confirm that this is what I need and whether I need the 8-SOP or 8-DIP version. I think it's the 8-SOP going by the photo. Also, does anyone know where I could pick one of these up in Australia? I'm going to try Dick Smith later today but I have the feeling I'll need to do go somewhere a bit more specialised.

thanks for any help
