The chip on wh ich the amplifier is
based, a Type LM3876, is a member
of the Overture family from National
Semiconductor. All members of
this family are pin-compatible and
mutually interchangeable. They are
typified by an internal protection
(calIed SPIKE).In practice, the difference
between them is the power output.
The series was described on the
basis of the LM3886 in an earlier
issue.
