STR-K760P SECTION 3 DIAGRAMS
3-1. CIRCUIT BOARD LOCATION THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this necessary note is printed in each block.)
STANDBY board POWER board
For printed wiring boards. Note:
� X : parts extracted from the component side. � a : Through hole. � f : internal component. � : Pattern from the side which enables seeing.
AC SELECT board (E51 model only)
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. � % : indicates tolerance. � : internal component. f � 2 : nonflammable resistor. � 5 : fusible resistor. � C : panel designation.
C Q BE These are omitted.
VIDEO board MAIN board DIGITAL board
BCE These are omitted.
TUNING board
HEADPHONE board
Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified.
Caution: Pattern face side: (Side A) Parts face side: (Side B) 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.
� A : B+ Line.
DISPLAY board
� B : B� Line. � Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. No mark : FM * : Imposible to measure 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. Circled numbers refer to waveforms. Signal path.
