Product details
All parts of this product are original, unpretentious and pure in quality; the use of high-quality original parts not only guarantees safety and quality, but also has a long service life, and more importantly, it is a strong guarantee that the actual performance can reach the design goals. Pursuing streamlined quality is our consistent aim.
1. Use original TT1943/TT5200.
2. The electrolytic capacitor signal main circuit adopts Taiwan, and the main filter capacitor adopts the gold NOVER audio special capacitor with a capacity of 2×10000UF. It adopts domestically made 25A and above rectifier flat bridges to ensure strong and continuous power support.
3. The resistance uses five-ring metal resistors, and the main loop uses five-ring metal film resistors with an accuracy of ±1% to ensure a good signal-to-noise ratio of the whole machine.
4. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. PCB quality.
5. Due to the use of direct coupling test amplification on this board, the entire circuit has no coupling capacitors, which reduces the distortion to 0.1%.
