Conclusions

  A high-quality tone block, assembled on the TDA1524 microcircuit, is easy to install and connect. A wide range of tone settings and the ability to turn on loudness will help you customize the timbre balance for almost any listener.

Summary: An excellent, budgetary tone block with power supply elements and voltage stabilization, which makes it almost universal. Unipolar power supply allows this preamplifier to be used in the on-board network of a car without any voltage converters, and small board sizes will help with installation in a compact case. You can buy a tone block in our kit-amp.com store.
