Note 2:
The MAIN board has been changed in the midway of production.
When the complete MAIN board is replaced, it might be necessary
to note the combination with the complete AMP board.
Refer to service manual supplement-1 for detail.
Note 1:
IC650, IC651 and IC652 on the MAIN board cannot replace with single.
When these parts are damaged, replace the complete mounted board.
