Hi to all members...
Please, if any user of any Xpander manufactured in Japan (second version) could make a detailed photo of its Power Supply board, it will be very useful to me. I released the schematics drawings just observing the board of the PSU I have, but there are some missing components and I don't have any idea about their values (mainly resistors and some capacitors).
I have been told that version of Xpander was sold mainly in Japan and Australia. The Xpander of my friend cames from Australia.
Any help will be very welcome.
Thanks in advance.
Sergio
