Three-Decade 15Hz To 15Khz Wien-Bridge Oscillator

  
In this circuit, an LM741 op amp drives a Wien-bridge network using two zener diodes as

an amplitude limiter. Range selection is done by switch selecting the capacitors (CI through C6) and tuning is done via a ganged pot. The output is about 8 Vpp max., depending on the setting of S2 and R6. R4 is set for maximum distortion consistent with stable output.
