This front end circuit also includes parts that provide bias voltages to both the positive and
negative halves of the output stage.
这前端电路包括提供正负各一半的偏置电压。
the positive bias network
consisting of R212, R213, R214, Z201, C209, and P202.
正偏压网络由R212, R213, R214, Z201, C209, and P202组成。
The P202 is used to adjust output to 0 volts DC.
P202用于调节中点为0V直流。
the negative half of the output stage formed by R216, R217,
R218, R219, C207 and Q204.
负偏压网络由R216, R217,
R218, R219, C207 and Q204.组成。
R219......try values starting with 47 Kohm or so,
decreasing the resistance for less bias current.
R219......的阻值可以试从47K左右开始,减少阻值则偏流减少。 |
