Using K2381 J407 FET

  The main circuit of the electrolytic capacitor signal adopts the famous brand. The main filter capacitor adopts the special capacity of the three battalions of electrolytic capacitors of 4×6800UF, and the full-wave bridge rectifier circuit ensures a strong and continuous power support.

The resistor uses a five-ring metal resistor, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio.

  The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality.

With fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers!

  The current advanced C1237 BTL horn protection circuit is used to effectively eliminate the impact sound and DC output protection functions of the open and shutdown.
Power supply voltage: dual AC12V
PCB size: 133*108
Maximum quiescent current: 0.1A
