Description
The amplifier board is provided in accordance with the original circuit design, signal-to-earth ground using 10 ohm resistor to interfere with processing, audio input is also 10UF capacitive coupling.
The board potentiometer if a direct positive turn the volume up, volume down is reversed, designed from the beginning, mainly in order to adapt to the circuit board mounting position in the box, if not a fixed installation of the housing board, you can use the line drawn from the potential installation location, then welded potentiometer 6 feet. (If you need to shop can defer processing cable)
The board can be pushed Europe 4--8ohm speakers, single speaker power 20W or less the best (caliber speakers with sound particularly bass relationship is very large, larger diameter pots bass better. Sensitivity the smaller the number, Speaker better push).
If you take low tweeter, you can take in front of the primary, or the easiest way is in the + input tweeter series about a 400V3UF Promise of capacitance.
Board size: 95mmX41MM
Input voltage: AC double 12-18V (you must double the output of the transformer)
1, power input needed: Dual output transformer (must be two-output) 12-18V
2, the original amplifier chip: 1876TF plastic package directly bonded heatsink installation without scruples insulation problems.
3, high-quality two-way coaxial sealed potentiometer 50K (clockwise to counter-clockwise rotation of the volume up volume down)
4, the input filter capacitor box
5, 6A rectifier bridge use, generally we are using 3A, the most critical parts simply can not cut corners, no heat!
6, using 2pcs RUBYCON 35V 10000uf large filter capacitor energy storage, to ensure the supply of the DC component of the instant subwoofer for bass storage violent jerk!
7, the potential can be drawn: in six holes original potentiometer welding pins are connected by cable to the potentiometer and the board, with screw cap on the potentiometer, can be fixed in your stereo or amplifier housing above!

1 x LM1876TF 20W+20W Dual Channel Stereo Audio Power Amplifier Board 20W*2 Amp
