The advantages of FET power amplifier:
1: High input impedance is easy to drive, and the change of input impedance with frequency is relatively small;
2: The input junction capacitance is small (feedback capacitance), and the change of the output load has little effect on the input;
3: High power utilization;
4: Strong driving load capacity.
5: Reasonable layout and wiring, high stability of the whole machine, good signal-to-noise ratio, and good performance of music details;
6: FET has better thermal stability, radiation resistance and lower noise.
7: High conversion rate and good high frequency characteristics;
8: The distortion of the FET is mostly even harmonic distortion, and the hearing is good;
9: The high, middle and low frequency energy distribution is appropriate, the sound has a sense of density, the low frequency dives deeper, the sound field is relatively stable and the sense of transparency is moderate, the layering, resolution and positioning are all good, and it has a good sound field space depiction ability
10: The output of the field effect tube is a power of 2 function of the input, and the distortion is lower than that of the transistor and larger than that of the bile duct
11: Electron migration in the solid lattice, with irregular motion (molecular dislocation or impurities), flicker noise (white noise) bulk noise.
