Features:
1. This audio power amplifier uses LM1875T chip, a simple external circuit,the audio signal is amplified.
2. Dual DC power input, do not support single power supply.
3. The coupling capacitor can take all capacitors from 2.5mm to 10mm.
4. The 330pF capacitor, which is used to absorb the over-high frequency clutter in audio signals, has been replaced by a sequential chip capacitor with a single-flower capacitor with better performance.
5. 100nF capacitor for power supply decoupling, has also been converted to monolithic capacitor, and vertical design and installation, only 2m away from the power supply lead!
