AUDIO ANALOG SIGNAL
THE COMPONENTS IDENTIFIED BY MARK ARE CRITICAL FOR SAFETY
REPLACE ONLY WITH PART NUMBER SPECIFIED.
VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE.(No INPUT SIGNAL).
ALL PNP TRANSISTORS ARE EQUIVALENT TO 2SA1015-GR UNLESS OTHERWISE NoTED.
ALL NPN TRANSISTORS ARE EQUIVALENT TO 2SC1815-GR UNLESS OTHERWISE NoTED.
ALL DIODES ARE EQUIVALENT TO 1SS133 UNLESS OTHERWISE NoTED.
ELECTROLYTIC CAPACITORS ( ) ARE IN uF/WV.
ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NoTED.
EX) 030- 3pF 330- 33pF 331- 330pF 333- 0.033uF
ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NoTED.
THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
