Details :


1. Using the original TDA7498 TL072
 
2. Front input capacitance and inter-stage coupling capacitor capacitance top Siemens 1UF, electrolytic capacitor signal main circuit designer from Taiwan, Japan Matsushita main filter capacitor capacitance electrolytic capacitors dedicated 2 × 2200UF, ensure strong support for a steady stream of power.
 
3. Use high-precision resistors chip resistors, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.
 
4.PCB using 1.6mm thick double-sided sheet, 2.0 oz copper thickness, HASL whole process to ensure the size of the current through the good performance. PCB-class quality.
 
5. fully enclosed dust-proof potentiometer, the performance is more stable, more durable than ordinary potentiometer.
 
6. Using red ring high-current inductors, to ensure crisp and powerful sound.
