SUBJECT: Vertical Circuit Modification
BACKGROUND: The vertical output IC301 has been changed from a TDA4866
to a TDA8351. The circuit change was made with serial numbers higher than
A95025160. The circuit change was made due to the failure of IC301 in some
cases during power up.
SOLUTION: The circuitry around IC301 was changed to meet the specifications
of the TDA8351.
