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. EX) PRINTING SIDE CIRCUIT IS SUBJECT TO CHANGE FOR IMPROVEMENT. NC = No mount of parts.
