One of the delay circuits using 555 time base integrated circuit

The power supply of this circuit adopts a half-wave capacitor step-down rectifier circuit, and the voltage regulator tubes vSl and VS2 stabilize
the voltage. The delay time of this circuit changes within 6~60s. By adjusting the potentiometer RP, the delay time can be changed, and the delay error is
less than 2%.
