Vinyl record player MM MC phonograph preamplifier board:
Use the special amplifier chip of vinyl record player, the effect is better than the amplifier board of NE5532 and other operational amplifiers. The circuit is designed with frequency compensation circuit, the sound frequency band is more balanced, the input signal filter circuit has relatively lower noise, and the rectifier filter voltage stabilizer circuit.
Note: The ground wire of the vinyl machine should be connected to the GND terminal of the power input of the amplified version or the GND solder joint as shown in the figure below, otherwise there may be interference.
Tips: The chip is a little worn, but it will not affect the use.
