Step 4 : Remove the Volume Knob. Step 5 : Remove all the screws. 3. Notes of Schematic Diagram (All schematic diagrams may be modified at any time with the development of the new technology) Note: : BAND switch : Variable Resistor - The voltage value and waveforms are the reference voltage of this unit measured by DC electronic voltmeter (high impedance) and oscilloscope on the basis of chassis. - Page 5 Components identified by mark have special characteristics important for safety. Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used. When replacing any of components, be sure to use only manufacturer's specified parts shown in the parts list. Caution ! IC, LSI and VLSI are sensitive to static electricity.
