Hi all, Bit if sheer terror here tonight. My Xpander is not powering on. The light on the power switch is not lighting up either. I tried a different power lead and a different outlet. Nothing. Was working fine earlier today. Is there a fuse on these somewhere I could check ? it is on a surge protector and all my other gear is working just fine. If the PSU has gone south - how hard are these to fix/replace? /m

Hi Mati, Don't panic! There is a fuse inside the Xpander. If you pop the lid, you'll see it on the power supply board. I have some photos of the PSU board in mine, for what it's worth: http://xpander.geek.nz/my-xpander-psu.html The PSUs were never the highest-quality part of an Oberheim synth, from what I can gather. If it isn't the fuse, it might just be a blown rectifier diode or something similar. If you can read a schematic and operate a multimeter, you should be able to track down the problem. Good luck!

you guys are life savers, the fuse was blown, so for $3.29 and a trip to Ace Hardware - the Xpander is back up and running! I love you all. /m

Easy, just undo the screws along the front edge and the ones at the top of the wooden end pieces and the whole front panel swings up on a big hinge at the back. Good to hear your Xpander is alive again! Sorry if I muddied the waters with pictures of my non-standard PSU... ;) Cheers, John :^P Mati wrote: > > > what is the procedure for opening the Xpander up?
