his be Super Bridge 120W Power Amplifier by IC TDA2030 for you like the circuit amplifies that use the integrated circuit. and Transistor BD249 or TIP31
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 …
Today we see the 19W stereo integrated amplifier IC-TA7240AP, ideal for small rooms Or use the car because the power supply only 12 volts.
This is TDA2009 bridge amplifier circuit BCL 18W,Supply volt = 23V 2A, it is 10 +10W STEREO AMPLIFIER integrated circuits interesting again the one number.
