The Hi Fi audio tone control circuit features tune smooth bass, and treble is not spicy, with a very low distortion. Please below : more Features
-Use low noise transistors
-Frequency response range : 20Hz-20KHz
-Total Harmonic Distortion Noise 0.001% at frequencies 20Hz-20KHz
-Maximum output voltage 14Vrms at frequencies 20Hz-20KHz
-Input sensitivity is 50mV
-The increase / decrease rate of bass : +/- 17dB at 20 Hz
-The increase / decrease rate of treble : +/- 17dB at 20KHz

اینم قطعاتش
بسازید حالشو ببرید
یکی از دوستام اینو درست کرده واقعا ازش خیلی راضیه
یه نمونه هم برا امپ ماشینش که خودش ساخته بود درست کرد
واقعا های فای هستش
خوشحال میشم شما هم بسازید
