Description

This is a bare bones amplifier. It has a large heat sink and it never shutdowns from overheating. The board design is quite simple as most of the work is done by the ST Microelectronics 7377 integrated circuit. The line level input connector is a standard 1/8" stereo connector, the power and speaker connections use CMM5-2 PCB screw down terminals. The screw terminals are typical for these types of bare amps and are a little weak (so don't over tighten, or solder on some wires).
