NOTE
THE COMPONENTS IDENTIFIED BY MARK
!
ARE CRITICAL FOR SAFETY.
REPLACE ONLY WITH PART NUMBER SPECIFIED.
BOLD 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.
w w w
EX) 030- 3pF, 330- 33pF, 331- 330pF, 333- 0.033uF
ALL RESISTORS ARE IN OHMS 1/6 WATT UNLESS OTHERWISE NOTED.
THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
EX)
PRINTING SIDE
"NM" AND "NC" ARE SHORT FOR "NOT MOUNTED" AND "NOT CONNECTED",
WHICH MEANS NO PART IS MOUNTED ON WIRING PATTERN OF PCB.

NOTE:
XY in "SCHEMATIC-a / PART-b:XY" indicates the target
location of the plug or socket, X=A to E/H/K, Y=1 to 4/5/8.
