STR-K7200 THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) For Printed Wiring Boards. Note: • X : Parts extracted from the component side. • Y : Parts extracted from the conductor side. • f : Internal component. • : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: Parts on the pattern face side seen from (Conductor Side) the pattern face are indicated. Pattern face side: Parts on the parts face side seen from (Component Side) the parts face are indicated. Caution: Parts face side: (SIDE A) Pattern face side: (SIDE B) Parts on the parts face side seen from the pattern face are indicated. Parts on the pattern face side seen from the parts face are indicated. • Indication of transistor. C Q These are omitted. BE BC E These are omitted. For Schematic Diagrams. Note: • All capacitors are in μF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums. • All resistors are in Ω and 1/4 W or less unless otherwise specified. • f : internal component. • 2: nonflammable resistor. • 5: flusible resistor. • C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. • A : B+ Line. • B : B- Line. • Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : TUNER • Voltages are taken with a VOM (Input impedance 10 MΩ). 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.
