• Allcapacitors are in µF unless otherwise noted. pF:µµ F
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ωand 1/4W or less unless otherwise
specified.
•¢: internal component.
•U: B+ Line.
•H: adjustment for repair.
• Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
