Energy Positive and negative cannot be corrected, the availability current can't exceed 5.5V, both of these violations might have brought IC damage. On-nick high-gain buffer cannot be altered to to board any component parameters, doesn't satisfy the parameters can lead to IC damage. Input line use shielded line, you are able to play an anti-jamming effect, eliminate clutter current seem.
Output for cmos tube BTL driver, the negative terminal from the left and right loudspeakers cannot be together, the four lines connecting towards the speaker is totally independent, and doesn't allow total access!
