McIntosh, which is unique in audio products, uses exclusive output transformers for both amplifiers and transistor amplifiers. Using output cattle has many advantages. The main thing is to ensure that the transistor can work when working under different frequency music signals. In a more reasonable linear region, the frequency characteristics and phase distortion of the output signal are lower, which is an important part to ensure the sense of hearing. But at the same time, it is more difficult to produce such an output cow, which is why no one has touched it in the DIY circle for many years. We have selected the current partner after comparing several different samples, and there is basically no difference in comparison with the output of the original machine. At present, the K134 field effect tube is used for the power output tube of the whole machine. The sound is beautiful and refined. This tube is only used in the market, and there are not many used, and it is only appropriate to exchange it for listening.
