1. Use original JRC5532.

2. The main circuit of electrolytic capacitor signal adopts famous brand, and the main filter capacitor adopts ELNA680UF*2+1000UF*6 to ensure strong and continuous power support.

3. The resistance uses five-ring metal resistors, and the main circuit 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 left and right channel input coupling capacitors are coupled with WIMA2.2UF, the treble is clearer and the sound is sweeter! The combination of high and low sounds is more perfect!

5. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.

6. The fully enclosed dust-proof potentiometer has more stable performance and is more durable than ordinary potentiometers.
