LM377 Power amplifier schematic

Various
needs of the amplifiers are all different. Different places and use
also requires a different power amplifier as well. For this time i gave
a circuit schematic power amplifier based on LM377 ic that has
similarities with the LM378 and LM1877. Power is smoothly small ouput
is 2 X 2.5 Watt and the impedance 4 ohms. Use of this amplifier
suitable for portable radio tuner that can be taken every where.
