2-1. SCHEMATIC DIAGRAM
SRS-Z050V
Note on Schematic Diagram:
• 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 Ωand 1/4W or less unless otherwise
specified.
• % : indicates tolerance.
•C: panel designation.
•U: B+ Line.
• Power voltage is dc 9 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.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production toler-
ances.
• Signal path.
