Stereo preamplifier with tone controls

It is a pre amplifier and audio control unit which will be a useful complement to our circuit amplifier makes. It is extremely easy to build special Philips TDA1524A due to the use of an IC.

Because it uses the control voltage, linear single gang can use pots which lowers costs and reduces Fehler.Es monitoring of switches control or microprocessor, if desired.
