Looking for X5DR replacement power supply

[Videot27]

Hi, all —

I recently located my long-lost X5DR, but unfortunately its power supply is still nowhere to be found. I have dug around at home and at work through various wall warts, finding a number of 12VDC power supplies. Unfortunately, every one of them has been tip-positive, and the markings on the X5DR indicate it needs a tip-negative power supply.
I did several Google searches for replacement power supplies, and so far, all the ones I've found which claim to include the X5DR in their compatibility list are tip-positive!
Does anyone have a reliable source for an appropriate power supply for my synth?

Thanks in advance for any usable information.
