I've got a 126 with a non-working tach and just stumbled on this. I'd be interested in either making one of these myself or just about any option besides a new tach amp. I may try and rebuild it to secure all the contacts if I can get all the gunk out of the cap. Anyone talk to him, know if he is still working on this and/or looking for prototype testers? Mentioned above he wanted a 126 to test on.
