The CLR and PS inputs are active LO, i.e., normally held HI (+5-volts), with a momentary LO signal to change the outputs. The Q output is cleared ... In the circuit shown, such a simple power supply requires that the DC voltage at the output of the bridge rectifier be very close to 9-volts. ... Schematic diagram of the electronics in the controller box in the warm room. ... An LED indicates which filter is selected.
