Well-scanned, complete manual. Contains the information needed for repair and maintenance.
It's great to be able to obtain a precious technical information for a real old equipment. The one I got helps me a lot in the area of wiring diagram to repair my antique. PDF gave me clear enough information to find out thr details. Thanks for giving me the oppotunity to be able to access to almost vanished informations.
Another excellent aquisition. Fine detailed manual. Thanks
Good quality for the scan, complete, but as usual for Tascam, not so comprehensive !
great manual readable & easy to downlaod to be recommanded
