Note on Printed Wiring Boards:Note on Schematic Diagram:
Y X : parts extracted from the component side.Y All capacitors are in ?F unless otherwise noted. p: pF.
Y Y : parts extracted from the conductor side.50 WV or less are not indicated except for electrolytics
Y: Pattern from the side which enables seeing.and tantalums.
(The other layers' patterns are not indicated.)Y All resistors are in & and 1/4 W or less unless otherwise
specified.
Y Indication of transistorY C : panel designation.
Note: The components identified by mark 0 or dotted line
Cwith mark 0 are critical for safety.
Replace only with part number specified.
Q
These are omitted
Y A : B+ Line.
B E
Y H : adjustment for repair.
YTotal current is measured with no cassette installed.
YPower voltage is dc 6 V and fed with regulated dc power
supply from battery terminal.
YVoltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
BC EYVoltages are taken with a VOM (Input impedance 10 M&).
These are omittedVoltage variations may be noted due to normal produc-
tion tolerances.
YWaveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
Y Circled numbers refer to waveforms.
