A80 classic MBL6010 circuit 6 times amplification fully balanced HIFI preamplifier with tone
Product Description:
All parts and components of this product are original products, and 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.
Product details:
1: Using original JRC5534 JRC5532, with gold-plated IC socket, you can freely replace other op amp ICs according to your preferences
2: The main filter capacitor adopts imported brand-name ELNA 4700UF/50V*2 capacitors, and the electrolytic capacitor signal secondary circuit adopts ELNA brand-name capacitors. Other capacitors are selected from Germany Siemens and WIMA.
3: The resistance selects 5-ring copper pin metal resistance to ensure a good signal-to-noise ratio of the whole machine.
4: PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full gold sinking process to ensure good passing performance of large and small currents.
5: This board has reasonable wiring, beautiful appearance, and low current noise. If you think other tone boards have loud current noise and poor sound quality, then this one is your best choice!
6: The circuit is exactly the same as MBL6010D, using more optimized components
7: With buffered input, the sound is very vivid and the density of the sound is increased. It is highly recommended that you give it a try
8: AP measured: 0-100K straight
9: Green Rubik's Cube 25M25-04 Pouring Bull
10: The standard configuration of the main volume potentiometer is the Japanese quadruple ALPS electric motor potentiometer
