Description
Circuit schematic like in Figure 1 above is Circuit Schematic 2N3055 Amplifier as 30 W OCL Integrated Amp. Eleccircuits site describe that In power amplifier circuit that will see that input circuit is connected as differential amplifier type. To control output of this circuit is zero volts. By use the feed back at base of Q4 through the R16.
The gain of this circuit is R16/R15. The signal from collector of Q3 will pass to base of Q6. Which acts as pre driver to amplifiers signal to the driver circuit that consists of Q5, Q7.
In setting the last output section is determined in forming the Quasi-Complimentary so the saving than the directly the pair complimentary as will see that we select to use the both 2N3055 transistors are pair output Q8, Q9.
