DMOs TDA7294 integrated amplifier guitar amp used for a variety of powerful sound, the tone control circuit TL071, TL072, TL074 op-amp ICs used

Voice in the introduction of control quite well GAIN, HI-MID, LOW-MID-BASS, TREBLE, VOLUME settings are all enabled electronic kompadent commercially available but quality potency little hard to find 4-ohm speakers and 2 x 12 volt supply voltage and 70watt power gives for 8 ohm speakers you can get 2 × 20 volt transformer power supply circuit using a full bridge diode used in place of 6 amps to me seemed a bit weak, I suggest using the bridge-diode
