Xpander power supply rev.2 problems

2009-06-29 by 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
