Dynaco circuit is classic and cleverly designed. The 6N2 tube has two functions, which are both voltage amplification and automatic balance inversion, and the 8.2K resistor is the finishing touch. This resistor is not only the cathode bias resistor of 6N2, but also constitutes an inversion with the secondary of the output transformer. The tail of the phase stage is also the loop negative feedback resistor! Three jobs in one, not only saving parts, but also reducing the additional noise and distortion of parts The power stage adopts a standard structure, the output power can reach 10W and the sound quality is excellent! There is basically a 90db or more The drawings are for reference only, the board has been improved, and the label on the board shall prevail! ! ! 6p1 is a beam-emitting tetrode, with warm sound, three-band equalization, strong flavor of the tube amplifier, it is very durable with a good transformer, and an audio tube with high cost performance. The 6N2+6P1 amplifier board needs an external power supply and a transformer. The power supply is filtered by CRC. The S/N of the whole machine can be as high as -107db A weighted (absolute residual noise voltage of 160uV). Such a low noise floor is basically only when the ear is close to the speaker. Can stop to a little noise. If you use the inductive filter to measure, it will be the icing on the cake. The parameters such as resistance, capacitance, voltage, and port are marked
