This is a 200 watts super bridge power amplifiers, include the transistors as based of circuit, so suitable for signals from the bass guitar. It’s a high power, durable and cheap. Use it in the house, the sound quality also is good. In Figure 1 we will see that the circuit consists of two section. First, include Q1, Q2, Q3, Q4, Q5, Q6, Q11, Q12 Second, include Q7, Q8, Q9, Q10, Q13, Q14 Which both section have the very similar form. But a few difference are: -At the section 2 is cut the protection circuit of the output transistors go …
