UK300BL single-ended tube amplifier, 8W+8W, no large loop feedback design! Different from the 300B machines of similar products in the market that are not designed for output, this machine is the flagship product of the store, and it is also the most high-end and most beautiful product! Each one is sold after welding, debugging and appraisal by our engineers! Please feel free to buy from senior enthusiasts!
The tuning mentioned by our DIY friends is, on the one hand, from the perspective of electricity, increasing the current increases the thickness of the sound, and increasing the voltage (within the specified range) can expand the dynamic range of the sound, the sense of hearing is not depressed, and the two ends extend naturally. . . Reduce the internal resistance of the power supply, make the transient state better, the tension of the low frequency is better, increase the coupling degree of the output cow, make the voice more emotional, and the female voice.
The belching sound is more obvious. The above terminology for enthusiasts may be difficult to detect by the instrument. If the above highlights are achieved, it is not that simple to make a beautiful sound. There is also a harmony of music. I call it music sense. All of the above. It depends on the dialectic of the ears, so many beginners who have a fever will inevitably turn up the volume, because the ears of the first brother are not sensitive enough and need a larger volume to stimulate the senses. But you have to know that amplifiers have linear distortion characteristics, so Chu Ge often misses the golden power of amplifiers! Always at a loss and struggling to find what is beautiful in the world. . . . . . The sound quality of the tube amplifier always depends on your own feeling, and there is no standard assessment! For the 300B-L single-ended Class A tube amplifiers produced by our shop, I also recommend that you be cautious, because the sound of the machine is also an artistic practice, and the appreciation is the same! However, the CD sky discs that you used to think were not very satisfactory can now be seen again. Of course, the 300B tube amplifiers launched by our store also have a certain sound dyeing, and the old ones can definitely be identified. After all, where is the price, compared with the British AUDIONOTE art Series 300B British tube amplifiers have completely different styles. It is comparable to green tea and black tea. The low frequency strength and control power of our own 300B are better. The medium and high frequency permeability is much better than the penetration of British tube amplifiers. The reason is my family. The 300B is a nominal British sound 300B-L tube, and the matching is Western Electric 91 circuit, the sound field positioning is similar, the line feeling extends at both ends of the British tube amplifier slightly better. . . . . Because of the difference in price, our 300B should be considered very good value, but many old local fans do not fully agree with and accept the sound of British tube amplifiers. Old fans think that the British AUDIONOTE300B tube amplifier is relatively new sound, while this machine is more. The traditional old British voice. . . . . . . . We will not make unnecessary arguments! The sound is like a mortal knowing it is warm and cold drinking water!

Amplifier tube: 300B (a pair of UK brand export tubes produced by PSVANE, a pair of high value of 2000 yuan, which is different from cheap tubes. Lower internal resistance, higher transconductance, more subtle emotional expression of music! More comprehensive)
Front tube: 6SJ7 (a pair of American antique RCA)
Buffer tube: 6V6 (a pair of antique radar tubes of the former Soviet Union)
Rectifier: 5U4GB(eh)
Coupling capacitor:
Mundorf, Germany
Connectors: all Taiwan-made gold-plated
Power transformer: British Red Bull notch chip 114*70 (300W, different from other imported iron core products, lower internal resistance and more flavor)
Output transformer: British amorphous iron core (Taiwan-made single crystal copper winding, which is different from ordinary wires, has better electrostatic effect, greater intermediate frequency gain, stronger texture, and more accurate positioning...)
Choke coil: British notched Red Bull iron core 76*50 (segmented winding method! Different from ordinary winding method, the three frequency is more balanced and the music taste is better)
