HELP - I desperately need the Bruel & Kjaer 2123/2133 Service Manual

Hello: Yes -- there is actually a 2133 Service Instruction! However, it was one of the last B&K published -- since they stopped distributing these after they were bought (the first time) in 1992. So, for instance, none were ever distributed for the 2035 or 2144 &c (both of which I own). To find one, you will likely have to deal with those who were once Service Centers (i.e. Pearl only has Instruction/Operating Manuals, not Service Instructions), such as Odin Metrology (once B&K's West Coast service shop) . . . !!
