The wonderful Eumig 940 Multiprocessor, on my home since I was a student, was rebuild a practically brand new specificacions a few days ago, with the new worm gear (courtesy of Maurizio di Cintio) and new toothed belt (purchased en Van Eck).
Now, too, with a "new" (40 year old but never used, "new old stock") amp part installed by Alex, a gift from Captain Crane, track two sounds as powerful as track one.
Very happy: machine is now ready for other 40 years of service!
