Make LM1875 sound better

LMl875 is a high-fidelity thin film power amplifier produced by the American NSC Company. It is very adaptable and can be used according to
OTIuOCI' and BTI. Different connection methods are used to make different forms of power amplifier ports. This article modified an amplifier B based on the Ocl-circuit recommended by the NSC manual.
After listening, I felt that the sound range was wide and the timbre was charming. In order to further develop I.
The potential function of M1875 makes the sound of this power amplifier more beautiful. After repeated tests during the production process, I gained two insights: First, the selection of
peripheral components is very important. Because this power amplifier circuit is simple and has few peripheral components , it is selected Although relatively high-end components , even
high-quality components , are more expensive, the total cost is not too high, and the sound quality is greatly improved. Second. In terms of circuit design and
production, some small improvements can also achieve very ideal resultsq
