Very well done, Uli. That´s an impressive load of work done to the meter bridge (and all the other things, of course). Over at groupdiy.com were a bunch of threads about TAC Scorpion restoration projects. If you haven´t seen them then check it out. In our german forum http://www.energyrecording.de we have something similar going on. Our member Benny made a fader and mute automation for his Scorpion. Be carefull to tell your son about that...

My own TAC Scorpion found a new home in the studio of Fool´s Garden Drummer Jan Hees in Bretten. It´s highly modified and sounds great. It can be heard on a load of released songs as he´s doing a lot of session work for different producers.

A few weeks ago I coincidentally stumbled across the same type of ribbon wire used for the i/o board connection, from a different manufacturer, though. Unfortunately I didn´t bookmark it. But it must have been either Mouser or RS Components. So everybody looking for these should wade through theirs catalogs. With a bit of luck it can be found.
