Odd memory saving problem on this one.

"The Xpander is a huge sounding vintage analog monster. This machine is incredibly deep, essentially it's like a 6 voice polyphonic modular with 12 oscillators, 5 envelopes, 5 LFO's and ton more. It has recently been serviced and refurbished with a new front panel, sides and power supply. All voices function and tune correctly and it passes the diagnostics routines. A small bag of spare parts (fuses and a couple of transformers) are included with the sale.

It appears this one has been modified with a voltage switch, allowing it to be switched from 100v, 115v & 130v to 200v, 220v & 240v. I've never had cause to use this, so I don't know if it works or not, but could come in handy for international buyers, world tours and so on.

In spite of all the work don ae on it, there is still one minor issue. Certain patch locations (any with a number 8 or 9 specifically) cannot be saved to from the front panel. Saving patches works fine when doing it from a computer, the battery has been replaced and internal diagnostic routines don't report any problems. It doesn't seem to be a mechanical problem either as the buttons function fine otherwise. I have no idea whats causing it!

That issue aside, this Xpander looks, sounds and feels great. A lot of time and money was spent to bring it to this condition and I'm sure the next owner will be very happy with it."
