for protecting the transistor when R4 is turned towards low resistance values. Resistor R2 and R1 forms a feedback network for the TDA2002 and C1 couples the feed back signal from the junction of R1 & R2 to the inverting input of the same IC. The diode D1 and D2 in combination drops 1.4 V to give the rated voltage (3.5V ) to UM66. UM66 cannot more than 4V. CIRCUIT DIAGRAM Power supply for the circuit. A well regulated power supply is essential for this circuit because

Premium Capacitor Resistor Transistor
Transistor A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material‚ with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) power‚ the transistor provides amplification of a signal. Today
