Subject:     WRONG Q712 IN UNIT - REPLACED WITH CORRECT PART
Symptom:     111
Last Update: 2000-11-14
Status:      Closed

Customer Description:
Customer complained of unit never working correctly. Right channel looked
OK, but, the NPN, Q712, in the left channel evidenced case damage.
Although most of the numbers were obscured by the damage, we could see
that it was a 2SC-----, not a 2SD2439, as in the right channel. This looks
like something installed at the factory. It does not appear that the unit
had been previously serviced.
Solution:
Installed the proper transistor, P/N 872902052.
