SERVICING NOTE
This set detects reel rotation by PH701 (photo sensor). FF/REW II10de
Reel rotation cannot be detected when the system control
board is removed, because PH701 is mounted on the
system control board. As a" result, the auto-off circuit and
tape end detection will misoperate. And, up and down of
