I’ve run into the issue with a lot of my second-hand archival playback machines, where I couldn’t find any free downloads of older service manuals, only paid. Of course, if you really hustle, everything is available free on the internet.
I recently got my hands on a very old Panasonic brand SV-DA10 DAT recorder. It's a beast, and works like a charm, with blazing fast rewinds and fast forwards, and a easy-to-use optical digital output. The machine is also manufactured and distributed under the same model by Technics. I stored the user manual here for my own reference, and everyone else who owns one of these classic DAT Machines.
