Resistor:

To differentiate the units of resistors, The 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 an ohm resistor. The resistor designated "Fusible" is a

fuse type resistor.

• Capacitor:

To indicate the unit of capacitor, a symbol P is used: this

symbol P means pico-farad and the unit of the capacitor

without such a symbol is microfarad. As to electrolytic

capacitor, the expression "capacitance/withstand voltage"

is used.

(CH),(RH),(UJ): Temperature compensation

(ML): Mylar type

(S): Styrol type

• The indicated voltage in each section is the one measured

by Digital Multimeter between such a section and the

chassis with no signal given.

• Schematic diagram and Wiring Side of P.W. Board for this
