NOTES ON SCHEMATIC DIAGRAM
1. Tuner
To differentiate the units of resistors, such symbol as K and
M are used, the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol
is ohm-type resistor. Besides, the one with “Fusible” is a

* capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the ca-
pacitor without such a symbol is microfarad. As to ale&o.
lytic capacitor, the expression “capacitance/withstand
voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
* The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas-
sis with no signal given.
