Notes
* To improve the performance of SL-1200MK2/1210MK2, the bottom structure and circuit are changed in the course
of production.
* After the change, SL1200MK2-A/1210MK2-A is indicated in the name plate asthe model of the set.
It is discriminated from before-changesetby -A. Also, checkthat the presentchange is of the setsafter the change
mark [] shown in the sirial No. sheet attached to the bottom and carton box.
_r This supplement service manual contains the bottom plate disassemblyprocedure, changepart No., circuit diagram,
P.C.B. and block diagrams. The other contents are the same as for the service manual of SL-1200MK2/1210MK2
already issued.
* Setswith cartridge (EPC-207C) are included in those for same areas.
* Since the power transformer fitting method isdifferent for setswith serial number sheetchange mark [], refer to
