The input port is connected in parallel with a 330P small capacitor. This method has two advantages: first, it can form a low-pass with R1, filter out some unnecessary residual Super high frequency, make the sound smoother, and also reduce the burden of the amplifier. The second is to eliminate circuit self-excitation. 2. A 10PF capacitor is connected in parallel to the feedback resistor, making the sound more transparent. 3. Use Bell networks and output inductors to prevent high-frequency self-excitation and compensate for the output. The above modifications, compared to many circuits, with a good power supply, can basically achieve over 99% performance of 7294. The voltage feedback is negative, and the performance is stable. Replacing different feedback capacitors can modulate different tones, suitable for grinding machines.
