Details
The tube preamplifier adopted whole aluminum chassis, reasonable and orderly layout, power wires and signal wires do not overlap, effectively reduce the risk of interference, and the transformer outlet close and connect with PCB terminal also accordingly. It is work painstaking work to design this product really.... PCB designing for the chassis strictly follows the principles that a point grounding. Used 6Z5P tube as a rectifier and multi-stage filter and MOS transistor IRF840 as regulator, it provide a stable pre-clean power. 3.15V-0-3.15V tube filament provide by AC power, so the sound quality is more flavor, while the background noise of the unit is 4MV only.
Features
1. Transformer is made of new high-silicon 0.5MM thick steel. High quality power transformer, 45W rated power, ensuring plenty of energy supply
2. Used a two-stage direct coupled amplification circuit extension, strong tube taste, wide frequency response and dynamic range.
3. Tuning with high-quality native Germany ERO coupling capacitance, two imported ruby or chemical capacitor as a filter capacitor.
4. Signal input used pure copper wire, RCA terminals is gold-plated. Lay the foundation for high-quality transmission of audio signals. Outlet material is nickel-plated brass.
5. Adopted precision metal film resistors, high signal to noise ratio, good stability.
6. Used Japanese ALPS 09 type volume potentiometer, no noise and longer life.
