doorbell, alarm and other power amplifier o circuit as shown in Figure 2-46. The simple circuit structure, excellent performance, high output power, easy debugging, it is suitable for amateur homemade. VTi ~ VT4 composed of complementary symmetry dual differential input stage, the output stage of BTL structure, the voltage amplifier stage with double push-pull voltage amplification so and BTL amplifier output stage adaptation. Amplifier output stage uses a small amplifier consistency pairing module TD5BC10, make debugging very simple o may also be similar to this performance of other high-power tube, paired.
