Hi, Lise, Some of the Teac and Sony machines could reproduce 4 tracks at once, which would speed up the digitization project. You'll need to reverse the two backwards channels in your DAW software. If you are willing to play back single channels and move connectors, almost any 1/4-track recorder from "back in the day" could do this for you as long as it has a 3.75 in/s speed. For the Tandberg, you might contact Terrysrubberrollers.com -- he rebuilds the part, but I don't think he fixes machines. Of course, there are several of us who could do this for you--on much better machines than the Tandberg, but I fear that the price is high.
