SERVICING NOTES
In this set, the S102 (POWER) detects REC/PLAYBACK on.
It is mounted on the MAIN board, and therefore the REC/PLAY-
BACK on cannot be detected with the MAIN board removed.
When making an operation check and voltage check of mechani-
cal deck with the MAIN board removed, fix the S102 at turn on.
