5-6. PRINTED WIRING BOARD — LED SECTION —
Note:
• 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
1
/
4
W or less unless otherwise
specified.
• U : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 9 V and fed with regulated dc power
supply from external power voltage jack.
• Voltage is dc with respect to ground under no-signal
condition.
no mark : POWER ON
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : ANALOG
J : RF
Note:
• X : parts extracted from the component side.
• b : Pattern from the side which enables seeing.
