FAST very good and clear a great unexpensive job!!! very recomended for all people who are preofessional or hobbists as me!!!!!!
 ;
Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.

Very good manual with clear electrical diagrams. Thanks owner-manuals.

Note: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise � � � � � specified. ¢ : internal component. U : B+ Line. H : adjustment for repair. Power voltage is dc 3 V and fed with regulated dc power supply from external power voltage jack. Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. Circled numbers refer to waveforms.
