Ability Level 3: IntermediateSelf-Assembly Soldering Kit

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.

  • 4 inputs: PU, AUX, Tuner and Tape
  • Bass, Treble, Balance and Volume (using clean DC control signals)
  • Frequency response: 20Hz-20KHz
  • Low distortion: 0.5%
  • Ideal for use as a booster for MP3 player, Walkman, etc

The 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.
