Introduction to X-10D Circuit
The famous Musical Fidelity company introduced a X10-D tube buffer preamp in the mid-1990s. Its excellent effect has caused a lot of sensation in the market. It is housed in a unique barrel-shaped shell in Hong Kong. Enthusiasts call it "Little Pig", which is added between digital audio sources such as CD/VCD/DVD/MP3 and the power amplifier. The horrible digital taste of long-term listening disappears, and the entire listening system will A sweet and delicate bile smell appears. This bile cushion can be used for the front and rear integrated panels, including the tone plate, to easily match the pre-stone front.
In the circuit, the classic triode amplifier circuit is used to work in a good sense of hearing. The whole circuit has no gain, that is, the buffer level. The circuit uses a deep negative feedback circuit at the output end, and the distortion of the circuit is achieved. Amazing indicators, reaching 0.008%, while the frequency response reached 10HZ-100KHZ, and the output impedance dropped to 200 ohms.
Based on the above circuit, we design and development of the biliary buffer, the design is simple and practical, the tone is warm, and the vocal is perfect. The biliary buffer can work with an AC12V AC. It is very convenient.
