What is a single ended bile machine and what is the difference between a single ended bile machine a

The single-ended bile machine is a bile machine that adopts a single-ended working mode in the final stage of the bile machine.

The single-ended machine has small power and distinctive sound, which is often said to be bile taste, but the power is small.

However, it is difficult to do a lot of power at the single-ended end, for example, with the same type of tube, it can only be 10W at the single end, and it is easy to do 30W when pushing and pulling, and it is easy to pay some price when the power is large, and at the same time, in terms of technology, the single-ended machine is more difficult to deal with than the push-pull machine. Therefore, single-ended circuits are often used in high-end machines, and push-pull circuits are used in popular machines.

It is the class A power amplifier of the tube, usually marked with KT88SE, KE34SE, 300BSE where SE refers to the single-ended bile machine, its circuit amplifier always works in an amplified state, so the distortion is particularly small, due to the small output power, you can use double-tube parallel or multi-tube parallel connection to increase the power.

The introduction of the single-ended bile machine is as follows:

The advantage of the gall machine is that the sound is sweet and soft, natural concern, especially the large dynamic range and good linearity, which cannot be easily replaced by other devices.

In the final stage of the gall machine, there are push-pull working methods, and there are single-ended working methods, because it is easier to obtain high power by using the push-pull mode, so it is a very common circuit form.

However, because the working mode of push-pull is a superposition mode, there is some distortion objectively, and there is addition and subtraction in the push-pull superposition, and some small things that are not originally available may be added in this addition and subtraction, and some small things that are originally subtracted at the same time, if a single tube is used in the final circuit to work in the single-ended class A state, there is no problem that the hail of the push-pull working mode cannot be avoided.

Therefore, the single-ended one is much better than the push-pull in terms of hearing, especially in some small details. However, it is difficult to do a lot of power in single-ended, and it is necessary to pay some price for the source of power to do large, and at the same time, in terms of process, single-ended machine is more difficult to deal with than push-pull machine.

The main differences between them are as follows:

1.Output mode: The single-ended bile machine uses one pair of output tubes for signal amplification, while the double-ended bile machine uses two pairs of output tubes for signal amplification.

2.Working mode: In a single-ended bile machine, the audio signal is only amplified by one polarity of a pair of output tubes, while in a double-ended bile machine, the audio signal is amplified by two polarities of two pairs of output tubes.

3.Output power: Since the double-ended tank machine uses two pairs of spring output tubes, it usually has a higher output power and can drive larger speakers, which is suitable for larger audio systems.

However, the single-ended tank machine uses only a pair of output tubes, and the output power is low, which is suitable for small audio systems.

4.Output characteristics: Single-ended tank machines usually output warmer, softer, and timbre characteristics similar to those of vacuum tubes, but with higher distortion. On the other hand, the output of the double-ended tank machine is usually more accurate and linear, but the distortion is lower.

5.Design complexity: Due to the use of two pairs of output tubes, the circuit design of the double-ended bile machine is more complex, requiring more components and space. However, since only a pair of output tubes are used in the single-ended bile machine, the circuit design is relatively simple.

6.Cost: Due to the high design complexity of the double-gear parallel rolling end bile machine, the cost is usually higher. The single-end bile machine has a lower cost due to its relatively simple design.

1. The gall machine refers to the audio amplifier of the world's lead tap tube. Some tubes are used for power amplification, and some are used for polishing, i.e., voltage amplification. The gall machine has his unique "bile taste", the voice is warm and durable, the feeling is good, and the atmosphere is good.

2. The gall machine is the oldest and enduring evergreen tree in the audio industry, and its significant advantage is that the sound is sweet and soft, natural and friendly, especially the dynamic range is large, and the sense of hearing is very distinctive.

The 6v6 tube is quite a good amplifier tube, and the advantages of using it as a power amplifier are high output power, low noise, and pure and full sound quality. In particular, the push-pull output is the icing on the cake. Not only will the crossover distortion be smaller, but the output power can work at full load without clogging, and the sound quality and timbre are better than that of single-ended.
