This be mini size power amplifier 2 watt OTL that use IC LM380. Be base readymade circuit for side sound work and the communication. Which use outside equipment adds least. The C6 can choose get many the value since 47uF to at 470uF which , have a voice good bass. The C3 use for decrease [...]

Output-clamp diodes are mandatory because loudspeakers are inductive loads. Output LR isolation is also used because audio amplifiers are usually expected to handle up to 2 mF load capacitance. Large, supply-bypass capacitors located close to the IC are used so that the rectified load current in the supply leads does not get back into the [...]

This circuit provides 16 watts of amplification. it is built using two LM383 power audio amplifiers. use suitable heat sinks with the ic. Part U1 U2 LM383 8 watt audio amplifier ic R1, R3 220 ohm resistor R2, R4 2.2 ohm resistor R5 1 megohm resistor R6 100k audio taper potentiometer C1, C7 10uf electrolytic [...]
