Xpander power supply rev.2 problems
|
kovalmoog67
Hi to all members...
I'm Sergio Koval, from Barcelona, Spain. A friend of mine gaves me his Oberheim Xpander that has a very big problem on its Power Supply, and I can't be able to find any info about it. It is the second version of the Xpander, manufactured in Japan, and the Power Supply is completely different from the service manual's one. I have released my own schematic of it, taken from the PCB I have, but there are some missing components (mainly resistors and capacitors) and I don't have any idea about their values. If any user of that version of Xpander could take a detailed photo of its Power Supply board, it would be very useful to me. I could get the values from that image. I have been told that version of Xpander was sold in Japan and Australia. My friend's one came from Australia. Any help or suggestion will be very welcome. Thanks in advance Sergio |

That xpander.geek.nz site is mine; unfortunately it hasn't turned into the rhodeschroma.com-like site I wanted it to be, but I'm happy to add new information to it so that Google can find it easily. Sergio, if you would like to send me your schematic I'll add it to the site. I'm pretty sure my Xpander's PSU is American, so the capacitor values might not be much use to you. I would think that these days it should be pretty straightforward to just replace the whole PSU with a new one, don't you think? I don't think there are any really weird voltages in there. Anyway, all the best with sorting it out. Cheers, John :^P -- John Pallister john@... john@... On Tue, Jun 30, 2009 at 6:52 PM, baumont987<geebeex@...> wrote:
