Stereo power amplifier based around two TDA2030 ICs. It has good input sensitivity, low distortion, good operating stability and full protection against overloads and output short-circuits.
It can be used as a booster amplifier for existing small systems or to drive a second pair of speakers besides the ones already connected to the system.
The board needs a symmetrical power supply of +/- 18Vdc, 3A and can be connected to loads of 8 or 4 Ohm. Large heatsink supplied. Kit version includes solder for assembly.Specifications
