Note:
•

All capacitors are in 

µF unless otherwise noted.

•

All electrolytic capacitors are rated at 50V unless otherwise
noted.

•

All resistors are in ohms.

Ω = 1000Ω, MΩ = 1000kΩ

•

Indication of resistance which does not have rating
electrical power is as follows.

Pitch: 5 mm
Rating electrical power 1/4W (CHIP: 1/10W)

•

: nonflammable resistor.

•

: fusible resistor

•

¢

: internal component.

•

: panel designation or adjustment for repair.

Note: “A” board schematic diagram is divided into 7 blocks.

Each block is named by its function and block
“number”. eg: Processor (001)
Joint connection between boards can be identified
using the block number followed by the grid's guide.
eg: -<PWR-OFF MUTE
002 : 4E
Meaning: Block 001 joint "PWR-OFF MUTE" is
connected to Block 002 joint "PWR-OFF MUTE"
located at grid 4E
