1. RESISTORS:
indicated in 2, %W, YeW,+5% tolerance unless otherwise noted k :kQ,
M : MQ, (F) : £1%, (G) : £2%, (K) : 210% (M); +20% tolerance
2. CAPACITORS:
Indicated in capacity (uF)/voltage (V) unless otherwise noted p : pF
Indication without voltage is 50V except electrolytic capacitor.
3. VOLTAGE, CURRENT:
[-_]: Signal voltage at( 45 W+ 45 W
L_]: DC voltage (V) at no input signal
Valuein( —) is DC voltage at rated power.
<=> mA: DC current at no input signal
80)output (1kHz)
4, OTHERS:
wp : Signal route.
@ : Adjusting point.
The A mark found on some component parts indicates the im-
portance of the safety factor of the part. Therefore, when replacing,
be sure to use parts of identical designation.
% marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit may vary
due to improvements in design.
