All parts of this product are original and original, simple and pure quality; using high quality original parts is not only a strong guarantee that the safety quality is guaranteed and the service life is long, but more importantly, that the actual performance can reach the design goal. The pursuit of first-class quality is the consistent purpose of the store.
Product details:
1.Using original TPA3116 and TL074
2. Electrolytic capacitor signal main circuit using chip electrolytic capacitor capacity 4 × 470UF, to ensure a strong source of continuous power support.
3. Resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.
4. PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, spray tin full process, to ensure good performance of large and small current through. First-class PCB quality.
5. The use of fully enclosed dust potentiometer, more stable performance, more durable than ordinary potentiometer!
6. The use of fully shielded high-current inductor, to ensure that the sound is crisp and powerful.
