Fig 7's circuit uses a high-quality audio amplifier as a current-voltage booster for ac signals. (The McIntosh- 75, with its transformer-isolated output and clean response, is a venerable favorite in research labs.) The LF356 op amp's loop is closed locally at a dc gain of 100 and rolled off at 50 kHz by the 200-pF capacitor.

In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based on the LM386 IC from National Semiconductor. The audio amplifier will be a self-contained, battery-operated component. In the second part of the lab you will construct a microphone circuit using a compact electret condenser microphone cartridge.

The main voltage gain of the amplifier circuit is made available from IC1, Q2 and Q3. Q4 and Q5 provide the essential current gain to run the output transistors Q6 and Q7. Transistor Q1 compensates Q4. D2 and D3 compensate Q5 and Q7. Zener diodes ZD1 and ZD2 protect Q2 and Q3 by limiting the output voltage swing of the IC.
