LM1875 Stereo With Preamp NE5532

The project uses two LM1875 ICs as the final amplifier, the circuit is made as simple as possible with the original circuit from the datasheet.  With a simple change using 2.2uf audiophiler input coupling capacitors.  The ne5532 is used as a non-inverting amplifier to amplify weak signals and also improve the signal quality given from the input. I put elco 100uf and the 100nF capacitor in the strategic section to reduce noise.  The circuit use simetrical -18v CT +18v DC Voltage. And the results of this amplifier are able to produce good sound, detail, warm and low noise.
