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 Ω and
specified.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 1.5 V and fed with regulated dc power
supply from external power voltage jack.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• X : parts extracted from the component side.
• b : Pattern from the side which enables seeing.
• Signal path.
