1. RESISTORS:
Indicated in n, %W. 25% tolerance unless otherwise noted k : kn,
M : Mn, (F) : 21%) (G) : $296. (K) 10% (M) :zzamoIar-m
2, CAPACITORS: A
Indicated in caoacitv (Fl/voltage (V) unles otherwise noted p : pF
Indication without voltage is 50V except electrolytic capacitor. 3
3. VOLTAGE, CURRENT:
E : DC voltage (V) at no input signal
(2:: mA : DC current at no input signal
4 OTHE RS:
@ :Adiusting point. _
The A\ mark found on some component parts indicates the im- f V
portance of the safety factor of the part. Therefore, when replacing,
be sure to use parts of identical designation)
This is the basic schematic diagram, but the actual circuit may vary
due to improvements in design.
SWITCHES:
s1: POWER 0N - OFF
52: SPEED 33l/3 rpm -45rpm
The underlined indicates the switch position)
