A complete STEREO integrated preamp and power amplifier board with 4 inputs, Tone Controls, Balance and Volume control. Based around a TDA1524A stereo tone/volume control IC and a pair of TDA2030 audio amplifier ICs.
FeaturesThe board has a power supply section so only a 2x14Vac/4A transformer is required (or 2 x 12Vac/4A with some loss of output power).
Kit includes all board mounted components (heatsinks, potentiometers, rotary switch with mounting board) and solder for assembly.
