Stereo LM1875 With Preamp
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.
