A stereo amplifier with a power supply, based on the LM1876 microcircuit, is the junior representative of the legendary Overture line of chips. This microcircuit in terms of sound quality and features, almost completely repeats the well-known LM3886, with the exception of power. If the task is to build a high quality, inexpensive and simple stereo amplifier, then the original LM1876 is the best choice! On the board of the module, in addition to the amplifier, there are power supply elements: a diode bridge, smoothing and shunt capacitors, which allows the amplifier to be connected directly to the terminals of the transformer with 2 windings connected at the midpoint.
LM1876 microcircuits are supplied in two types of packages: insulated and non-insulated. In case of ordering a non-insulated housing, the set includes mica, insulating gasket
