    Stereo Audio power amplifier 2 x 40W - 80W

    I have tested the TL071 opamp preamp it is working great , but the sound when i connect it to the speaker it is really low, i mean it is behaving like a headphone , i think maybe the power amp would increase it .today i will build the Power amp and update you.

    Another INVERTER we can talk about..

    Hello everyone . I found a circuit to generate a modified sine wave. Can it be used with the inverter as an oscillator . THe Opamp just filters the modified digital sine wave . so if you dis regard the opamp it gives a approximation sine wave or a modified sine wave , digital sine wave ...

    Stereo Audio power amplifier 2 x 40W - 80W

    IF i only use the Circuit that you have posted in and connect it to my power amp , it will have volume control . but will it have enough power to drive my power amp , and do i have to use the LM386 for that , or just use your TL071. One more thing i have made the PCB's for the LM386 and two...

    LM386 is also an audio opamp . well the input is from a electret mic , i toook both diagrams from the PDF . Both the documents agree that each of them might be used together. I only want simple volume control and less bulky circuitry , how can i impelmet TL071 in it k17.pdf kit98.pdf

    Stereo Audio power amplifier 2 x 40W - 80W

    Hello Audio Guru , i have almost built the PCB and refined it , for the 80W Stereo That i posted the first time . i am making only a mono version for the university project. so i also need to make a preamplfier . So i had a preamplfier i made some time , but it had very bad distortion , it was...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    IF we make a sine wave inverter with making sine wave instead of square wave and and use mosfets in our design 4 parrallel mosfets oen side and 4 parallel mosfets other side, IT willl minimize heat dissipation and we will have a sine wave inverter. BUt making a modified sinewave wave , a digital...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    But this one is battery dead as well as circuit dead , i used it 4 years back to run television , even a computer , it was known here as a 486 computer UPS You are right i think it is a Modified Sine wave . we can make a modified sine wave and then step up without heating and also can use...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Well amazingly i found a UPS Inverter . and well it is quite complicated , dual layer PCB and all that stuff . i cannot use the parts in it , beacause it is my dad's office UPS and it is dead . so here are some of the things i found . * 4 mosfets IRF240 , 2 sets in parallel . * BUZ11 mosfet *...

    Convert 0-30V 3A PSU to 5A or more

    You Said this earlier for the 3A PSU and by the way how is the heatsink for the 3A PSU.

    Stereo Audio power amplifier 2 x 40W - 80W

    As the Site says '' A good starting point is using 4 turns for each primary (that is, 4 turns, centre tap and another 4 turns IN THE SAME DIRECTION). To calculate the number of turns of the secondary winding, multiply by the turns ratio. For example, if you want to build a +/-30V supply, the...

    Convert 0-30V 3A PSU to 5A or more

    THe TIP 31A is a change , the Two Paralleled 2N3055 is a change and the UA741 right.. I am making the 3A one , which value of capacitor do i use. The Picture of my another heatsink is as follows.with and without fan
