Ordering guide:
Chip options: LM3886 or TDA7293Type A: Without potentiometerType B: with potentiometerType A with acrylic: no potentiometer + acrylic guard plateType B with acrylic: with potentiometer + acrylic guard plate
Note: Be careful not to short-circuit the wires when using.Choose one of LM3886 and TDA7293 chips, the price is the same.This model of scaffolding newly upgraded capacitors, strengthened the optimization of wiring, and upgraded from the original Panasonic resistors to Dale resistors.product detail:1. Power: 60w+60w (3886); 100+100w (7293)2. Input voltage: double AC transformer 18-32V, 150w or more is the best3. Length, width and height=130mm*120mm*55mmSense of hearing:Compared with the PCB board scaffolding line, the human voice is closer and more poisonous, and the high pitch is more natural. The sound rendering has become richer. Everyone's ears are different, and the sense of hearing will be different. The above represents a personal sense of hearing.Note: If the buyer has no special requirements, the current delivery is the latest improved version of the large capacitor placement (the new version of the capacitor sleeps).
