Wien Bridge Oscillator, with oscilloscope and sound

This is a relatively simple oscillator circuit, the Wien Bridge Oscillator. I am putting the output to an oscilloscope (sorry about the blurry screen; that's the best my camera could do) and an amplifier, so you can see the wave form and hear it as I adjust the frequency.

The circuit is unusual for using a light bulb to maintain steady amplitude. The frequency is determined by two capacitors and two resistors. I used a stereo potentiometer in place of the resistors so the frequency can be tuned.

@piriya57 Well the grid sounds similar when listened to through a transformer (DO NOT ATTEMPT)

thats cool would have loved to see the circuit as well

IT WAS GOOD BUT NOT CLEAR...
