T1: 117V/230V AC primary to 18V-0-18V, 2A secondary transformerĪll full-size images and PDF of this post are in this Ebook below.C6, C7: 4,700uF 50V, Electrolytic Capacitors.Recommended: What is capacitor? Principle working, types and how it works Read next: Learning electronics for beginners for review. Next, The filter capacitor- should have over 4700uF 50V as characteristics the standard power supply circuit that uses in normal.Read other sites: 30 Watt Amplifier Circuit using Transistors Then, we will have the results as the DC volts + 24 volts for this circuit. Next, passing the bridge rectifier circuit and filter capacitors. So, we use the transformer that has a secondary coil is 18-0-18V at 2 amperes. The main DC power supply of this project is + 24 volts up to 2 amperes.Then, insert correctly the output transistor to this project.Related: NE5532 Pinout Datasheet Dual low noise op-amp You should reduce the range of meter to lower respectively, until the lowest, with the certainty that can read really is zero.
In setting, the last output section is determined by forming the Quasi-Complimentary.
Which, Q6 acts as pre-driver to amplifiers signal to the driver circuit that consists of Q5, Q7. Then, the signal from the collector of Q3 will pass to the base of Q6. By using the feedback at the base of Q4 through the R16. To control the output of this circuit is zero volts. In the power amplifier circuit, you will see that the input circuit is connected to the differential amplifier type.

Which is popular extensively at this time. To begin with, the tone control section is determined as the feedback tone control type.
