[1] Notes on schematic diagram

• Resistor:
To differentiate the units of resistors, the symbols K and M are
used. The symbol K means 1000 ohm and the symbol M means
1000 kohm. The resistor without any symbol is an ohm resistor.
• Capacitor:
To indicate the unit of capacitor, the symbol is used.
The symbol P means pico-farad and the unit of the capacitor with-
out 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
(PP): Polypropylene type
