BRZHIFI PAT A21

The power tube of this machine adopts 6p13 side-thermal oxide cathode beam four-pole power tube, which was originally used for power amplification in TV with high Evaluation Rate. According to its high sensitivity power characteristics, it only needs a small signal to give strong high frequency power, and its performance can catch up with EL34 bile machine. The front stage uses 6N2 input, the sound color of the whole machine is round and natural, the sound bottom is mellow, sweet and warm, especially when listening to human voice, the performance is very rich, transparent and durable. It is suitable to listen to human voice, piano sound, string music, guzheng, etc.

The circuit structure of this machine adopts gallstone mixture, which is currently used in many audio and fever machines. Its advantages lie in good linearity and large dynamic range, and it can effectively exert the unique flavor of the electron tube. On the other hand, it saves the complicated output transformer. The front stage of this machine adopts voltage amplification single-terminal circuit composed of 6N2 and 6P13, and the last stage adopts high-power transistor for simple current
amplification, which is called 0dB amplifier, the driving capability of the transistor. The purpose is to take the attractive tone color of the electron tube and the driving capability of the transistor. Due to the high-voltage power supply of the push-grade electron tube, A21 has good dynamic performance and its output power reaches 15W per channel, Home use and office use are great choices.
