Note:•All capacitors are in µF unless otherwise noted. (pF:  µµF)
Capacitors without voltage indication are all 50 V.
•Indication of resistance, which does not have one for rating electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP : 1/10 W)
•All resistors are in ohms.
•f
: nonflammable resistor.
•
Ï
: fusible resistor.
•f: internal component.
•
p
: panel designation, and adjustment for repair.
•All variable and adjustable resistors have characteristic curve...
