The logical continuation of the kitON's power amplifier on the LM1875 is a full power amplifier with timbre unit.
On a small size of the board, it was possible to place a full-fledged power supply unit, which means that the power supply is connected directly to the secondary windings of the transformer with a branch from the middle. Also on the board is a perfectly sounding timblock, with volume / woofer / midrange / treble, which will allow you to adjust the tone balance for any music lover.
Original LM1875 ICs are used as well as exceptionally high quality components!
The supply voltage is variable 2x10 ... 18V with the connection at the midpoint.
The power depends on the voltage and load current of 15-25W
