Figure 5.9. There are two input terminals on the left. The lower one is grounded. The upper one connects to the negative end of a capacitor labeled C2, 2 u f. The positive end connects to the base of Q1. The base connects through a resistor, R1, 91 k ohm to Vcc. The base also connects through R2, 10 k ohm, to ground. The emitter connects through R4, 6.2 k ohm, to ground. The emitter also connects to the positive end of C2, 4.7 u f. The negative end connects through R10, 1 k ohm to ground. We will return to the junction of C2 and R10 later. The collector of Q1 goes through R3, 82 k ohm to Vcc. The collector also goes to the positive end of c3, 2 u f. The other end goes to the base of Q2. The base of Q2 goes through R5, 24 k ohm, to Vcc. The base also goes through R6, 4.7 k ohm to ground. The emitter of Q2 goes through R8, 1.2 k ohm to ground. The emitter goes to the positive end of C4, 10 u f. The negative end goes to ground. The collector of Q2 goes through R7, 5.6 k ohm to Vcc. The collector goes through a capacitor, unmarked, to the upper output terminal. The lower output terminal is grounded. The collector also goes through R9, 47 k ohm to the junction of C2 and R10.
