Simplified diagram of the twin T lamp stabilized oscillator. No component values are given. The amplifier is represented by a triangle with the point to the right. The output is on the right and the two inputs are on the left. The output goes through a tungsten lamp to the noninverting input. The noninverting input goes through a resistor to ground. The output goes through a capacitor to the inverting input. The output goes through one resistor, then another resistor, to the inverting input. The junction of the two resistors goes through a capacitor to ground. End verbal description.
