The A mark found on some component parts indicates the
importance of the safety factor of the part. Therefore, when
replacing, be sure to use parts of identical designation
2K marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit may

noted k:kQ,M:MQ, (F); 1%, (G): £2%. (K);*+10%, (M):
20% tolerance.
CAPACITORS :
Indicated in capacity (u F) /voltage (V) unless otherwise noted
Pp: pF.
Indication without voltage is 50V except electrolytic capacitor.
VOLTAGE CURRENT :
3: Signal voltage at (75W+75W. 49) output (1kHz)
Ti: DC voltage (V) at no input signal.
mA; DC current at no input signal.
OTHERS
: Signal route.
The A mark found on some component parts indicates the
importance of the safety factor of the part. Therefore, when
replacing, be sure to use parts of identical designation.
sk marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit may
vary due to improvements in design.
