    Audio Amplifier Plz check this out

    Thanks audioguru! but actually this is the circuit made on Multisim. Actually the power amp section of this circuit uses LM380 instead of teh one used in the diagram above. Sorry for not mentioning that, Now tell me will it work or not? Thanks and Good Bye!

    Simple Parallel Combination Question

    Well! My friends donot think that im joking here!!!! I know all that which u told me. Well! i have seen that theoritically its working but practically not perhaps. I made the same circuit which i have drawn in my 1st post above. When i checked it thru the Multimeter, the result was awful...

    Analyzing my amplifier project

    Hi Audio Guru! my dear friend! i know this thing already, but when i went to an electronics shop, he gave me a trimmer of 100uf. so that is why im using it here. dont u think it is possible? sorry but i really didnt understand what u r trying to say here. My circuit gives an amplification at...

    Voltage that drives the speakers

    HI Guys! well! i have a simple question to u. I know this thing that a microphone provides u with some AC voltage in an audio amplifier. But what is that voltage in an audio amplifier, that goes into the speaker in order to drive it. Is it AC or DC? Thanks in advance!

    Problem with my breadboard

    Hi Guys! im facing a terrible problem here. I have designed a circuit that works very well according to my software simulation. Remember im using MULTISIM 2001 for the circuit simulation. But when i tried to make the same ciruit on my breadboard, it just didnt give me the same results, infact...

    LOAD RESISTOR IN A MOSFET AMPLIFIER

    Thanks a lot Audioguru! your help has really improved my ideas and designs. But one thing that i always want to ask to you is How to add an AC negative feedback in an amplifier circuit. Can u give me an example please. After adding it, according to u, it would give me sufficienlty low output...

    LOAD RESISTOR IN A MOSFET AMPLIFIER

    Hi Guys! thanks a lot for ur help audioguru. But still i want to ask u one thing. I have read that the drain followers are used when u need a very little voltage gain and i need a high voltage gain that is why im using source followers, then why are u compelling me to use drain followers...
