does "clean" mean "erase"? -- Since they are still around, see if you can get a manual. It will probably be $100 to ship the unit, even if you get it for $50. They may support cleaning a tape w/o certifying it. Also check if there are consumables (the older Kybe units have a loop of cleaning tape that I haven't been able to find a source for) required for this unit. I didn't see any supplies listed on their web page.
