Low distortion Wien Bridge Oscillator - High Performance Version. Selected values for 1,000 Hz frequency output at 26 volts peak to peak. C1, C2 are precision film capacitors for low drift and distortion. IC1 is an OPA1612 ultra-low noise and distortion audio op-amp. VR4 is an external 10K potentiometer for adjusting output level. R2, R3 are for adjusting series and parallel bridge frequency circuits. R1 adjusts the negative feedback of the oscillator. L1, L2 are 14 volt incandescant bulbs used in the negative feedback circuit. Changed resistors to 1206 low noise type. Revision 1.1
