Parts
List:
R1 = 560 ohm
C1 = 1000uF/16V, Electrolytic
C2 =
100uF/16V, Electrolytic
C3 = 330nF, Ceramic
Z1 = 9.1V, 0.4watt zener
Q1
= ECG184, NTE184
Notes:
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 9volt cassette recorder and
other stuff.
