Schematic principle of debugging circuit of tube amp
As shown in the figure, it is a general-purpose tube power amplifier circuit that is simple and easy to manufacture and has strong interchangeability of tubes.
Circuit principle: The voltage amplification stage uses SRPP single-ended push-pull circuit. The inverting push stage uses a common cathode long tail inverter circuit. The power stage uses an ultra-linear current amplifying circuit. The above three circuits are practical circuits that are currently popular and have good electrical characteristics. The difference is that the large loop feedback is connected to the voltage dividers of R2 and R3, not directly to the cathode of the voltage amplification stage. Practice has proved that this effectively overcomes the ultra-low frequency oscillation of the amplifier.
