THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.

6-2. CIRCUIT BOARDS LOCATION(In addition to this necessary note is printed in each block.)

For schematic diagrams.

Note:

		•	All capacitors are in µF unless otherwise noted. pF: µµF
			50 WV or less are not indicated except for electrolytics
			and tantalums.
		•	All resistors are in Ω and 1/4 W or less unless otherwise
			specified.
		•	%		: indicates tolerance.
		•	¢		: internal component.
		•	2 : nonflammable resistor.
	BD board	•	1 : fusible resistor.
SW board		•	C : panel designation.

		•	U : B+ Line.
		•	V : B– Line.
		•	H : adjustment for repair.
		• Voltages and waveforms are dc with respect to ground
			under no-signal (detuned) conditions.
			No mark : FM
			(	)	: PLAY
			<	>	: REC
		• Voltages are taken with a VOM (Input impedance 10 MΩ).
			Voltage variations may be noted due to normal production
			tolerances.
		•	Waveforms are taken with a oscilloscope.
		•	Circled numbers refer to waveforms.
		•	Signal path.

Note:

•	X	: parts extracted from the component side.
•	¨	: Through hole.
•	¢	: internal component.
•	b : Pattern from the side which enables seeing.
•	p	: parts mounted on the conductor side.
