The invention provides a non-dead time power amplifier output-stage circuit and relates to an electrical technique. The circuit comprises a first power tube(1) and a second power tube(2) which are connected in series, and a first drive circuit(10) and a second drive circuit(20) which are connected to control ends of the two power tubes respectively, wherein the Q point is the output end; the first drive circuit(10) comprises a first drive tube(11) and a second drive tube(12) which are connected in series; and the second drive circuit(20) comprises a third drive tube(21) and a fourth drive tube(22) which are connected in series. The circuit has the advantages of eliminating the distortion and reducing the total harmonic distortion of the system.
