The 6SL7 (6N9P) tube serves both the functions of voltage amplification and automatic balanced phase inversion, and the 1K resistor is the finishing touch. This resistor is not only the cathode bias resistor of 6SL7, but also the tail of the phase inversion stage with the secondary of the output transformer. It is also the loop negative feedback resistor! One person and three jobs not only save parts, but also reduce the additional noise and distortion of parts. 3: The power level adopts a super linear (UL) structure, which gives consideration to the balance between efficiency and distortion. After a little modification, the output power can reach 10W THD=0.4%, and the damping is greater than 4.0. With such a simple line, it is really superior! 4: The power supply is much less. With only CRC filtering, the S/N of the whole machine can be as high as - 107db A (absolute residual noise voltage 160uV). Such a low bottom noise is basically a little noise when the ear is close to the horn. If the inductive filter is used for measurement, it will be a icing on the cake. 5: Plate size 240 110mm, plate thickness 2mm. The resistance and capacitance parameters are marked on the board. The circuit performance is excellent, the wiring is reasonable, and the
