Note:
The difference between the differential and voltage levels is large, and the quiescent current of the final stage is in principle greater than 0, avoiding crossover distortion.
Do not increase the quiescent current of the final tube, please adjust it from 5ma to 30ma. (Test point data suggest 5mv can be adjusted to the contrary).
