12Vto 9V converter Circuit schema

Parts List:

R1 = 560 ohm

C1 = 1000µF/16V, Electrolytic

C2 = 100µF/16V, Electrolytic

C3 = 330nF, Ceramic

Z1 = 9.1V, 0.4watt zener

Q1 = ECG184, NTE184

To get a more precise output voltage, replace zener diode Z1 with 10V and R1 with a 1Kilo ohm
potentiometer. A Coolrib for Q1 is optional. Simple circuit to power your 9 volt cassette recorder and other stuff.
