M3886 is a mono, high-performance audio amplifier IC produced by National Semiconductor (NS) Corporation. The maximum continuous output power is up to 60W. From its introduction to the present, it has been loved by a large number of audio enthusiasts.
The power amplifier adopts a monophonic design. The power amplifier section has one board per channel, and the power amplifier board can be connected in parallel, and can be selected through a white non-inductive resistor. All components on the board are carefully selected. The circuit board adopts double-sided blue boards with reasonable wiring and beautiful appearance. BENNIC audio series coupling, outstanding effect.
Audio input BENNIC coupling capacitors look good, and I have a few samples, this kit default use Siemens layer cake to do coupling, dislike friends can use the original WIMA coupling or high-level electrolytic coupling such as BP-P or BP- S top series. The power input is not an AC input. From left to right, it is the positive power ground negative power supply.
Recommended supply voltage: dual 20-30V (secondary transformer output voltage double)
Recommended minimum input voltage: dual 18V maximum input voltage dual 40V voltage (measured 3886 ends)
Suggested transformer power: 100W (requires actual output power!)
Recommended filter capacitor capacity: greater than 6800UF increase can improve the bass impact, the premise is that the bass does not appear Xiaobo phenomenon.
