Tone Controlled Preamplifier Circuit TL072 Opamp
Preamplifier circuit TL072 op amp based on the previously shared “NE5532 Preamplifier tone control” circuit is controlled according to the deeper and a little more powerful stereo two-channel preamplifier and solid bass, treble, balance, volume control. TL072 op amp tone control preamplifier circuit power supply +-12v (7812 7912 negative positive regulator, the regulator) low flow for taking small 12v control by connecting to the circuit in series.
