Top class product, I printed it out on A3 paper and it is clear and very easy to follow.
Cheaper than buying a new radio!
;
is part of the manual is very useful for repairing
Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components

Hello.
This paper enable me, to bring this lovley Scope into Function.
Without this Page, i have no cance to make this finish.

7. GENERAL INFORMATION
7.1 SINGLE OPERATION METHOD
Single operation method and inputlevel.
The procedure and the input level of a single operation are shown below. 1. R85 are shorted by 1k�. 2. A point of the figure below in four places is connected. GND is not common because it is independent with chassis GND (GND of the amplifier), B1GND, B2GND, and B3GND. The potential of B1GND, B2GND, and B3GND is done by connecting A point in four places as well as chassis GND. 2. The power supply of the product is turned on. 3. the terminal CONT (2 pin of CN3332) are controlled respectively by the following voltages. CONT 5V ON ON
12V RY MUTE ON OFF
0V OFF ON
4. The signal of 10mV is input from input terminal (JA3333), and the output is confirmed with speaker terminal (CN3331). Note : If the music signal is input directly to input terminal (JA3333) with CD PLAYER etc. , the output becomes a large volume because there are 40dB GAIN of the amplifier.

Caution when disassemble. Even if the power supply code is pulled out from the outlet, neither C11 nor C12 of AF ASSY are discharged. Please discharge C11 and C12 of AF ASSY by the resistor of 100 � or more before removing AF ASSY or POWER SUPPLY ASSY. There is a possibility to destroy the transistor, and Please discharge by the resistor of 100 � or more.
