Great product, helped me to restore vintage walkman cassette.
Just some pictures could be little bit more sharp and contrast
Thank you

I love older radio's and the service manuals that are sometimes hard to find. Was able to find a manual quite easily on this site.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) For schematic diagrams.
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. � 2 : nonflammable resistor. � C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. � U : B+ Line. � V : B� Line. � 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. � Signal path. F : FM
For printed wiring boards.
Note: � X : parts extracted from the component side. � b : Pattern of the conductor side. Caution: Pattern face side: (Conductor Side) Parts face side: (Component Side) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.
