Sorry to revive an old thread, but currently I'm also desperately looking for a service manual for the EMT 252. Couldn't find it here inside the media folders. Could anybody please help me out? My email is toni.hinterholzinger (at) hfm-nuernberg.de
For those looking for EMT251 manual/schematics: Schematics and Manuals
There are more EMT manuals hosted, but no 252, I´m sorry, Toni.
(cheers from Baden Baden, we met and talked a bit at Daniel´s sheer pleasure of sound workshop)
