100W Audio Amplifier with Mic Input

I want to make my own audio amplifier with the specs of

100Watts , (stereo) 50Wmono 50WSstereo
mic input
equalizer (bass mid treble) (high mid low)
Transistorized ( i must not use IC chips)
maybe 20khz-20khz. (i dont know, what can you suggest best?)

i have no idea how to start it, can anybody help me with it, im not an engineer yet. i just want to make my own amp. ^_^ . it would be helpful if you can send me an schematic diagram and other useful stuffs. thanks in advance.

20kHz to 20kHz? What, are you making this amp for a dog???

Just kidding

i didnt spot that either lol

this is very big circuit ( mic pre amp, head pre amp, pre driver, various type audio mixer, tone control, after tone cont driver, power amp and power supply circuits etc). can you build it by proper way.

Buy one from ebay cost you less $19.00 much easier weve all given up with that idea of building new amplifiers Why ?? (There’s your answer Ebay ) hence why National Technics and all the well known well made amplifier companies have gone bust (Closed their doors ) No Info No Nothing

Clever huh Only one slight problem No ones going to service or repair them for you for under £50.00 to £80.00 in the Uk Why ?? (because it took us over 25 to 30 years to become professionals ) That’s going to be your next answer

And what’s the next answer going to be the same for designers because they too are not going to sit and design something for you for less than £50 to £80.00 per hour Why is that (because they too didn’t go to university and college to sit and design for someone to sell top grade high quality amplifiers for the likes of £19.00 ) in other words penuts

That’s why

So they not looking to clever there either are they

Finally that’s why all your shops are closing and they too are sick to death of working their guts out for peanuts as well

So now you really have got problems haven’t you So there you go that’s what you get for no investment That’s what you get for cheap and lovely ending There’s all the information on the net

Now you can all go way and make them yourselves because you are so clever to clever for us you see

ha ha ha ha ha cool joke love it
At last and what makes this even funnier is they going to stop your dole money as well ha ha ha ha ha


Love it even more


And that spells the end of Daves life long gaming periods sitting on his backside, thinking but not washing and bathing , living like a flipping pigh THAT THE DOLE OFFICE ARE GOING TO LET HIM GET AWAY WITH NOT WORKING, ANNOYING LOADS AND LOADS OF PEOPLE

AND ALSO LITTLE MARK ROLPHS BILLGERANT ATTITUDE WHEN YOU TELL HIM TO GO WAY AND LEARN SOMETHING whilst he sits arguing the toss with you like many other people too I just love it

Classic ending

Correct again that’s exactly what they have done Cant say I blame them or the teachers for leaving you high and dry at colleges universities as well Sick of the attitudes , sick of the working conditions , sick of the pay , sick of the long hours , sick to death of the no pensions story sick to death of the abuse , violent attitudes the lot , sick to death of not being paid on time , sick to death of the poor quality standards and the high demands they are expected to meet with ultra low budgets Cant be done anymore

Hence most people are now leaving this country Its camer blairy ruined

Expecting people to sit here and do this for nothing Any idea how long it takes to put something like this together ? Try apprximatlley a month or so Just to sit down and get to the stage of biulding this

You dont honestly expect people to do this on a non paid basis do you ?? Your are Nuts !! Who pays the devlopment costs Who pays for the matarials Who pays the bills Who Pays for the parts The time The PCB The sofwtare The lot

Open to ideas from you cant quite see how you think this is going to work myself

Wait I know silly old me

I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident: that all men are created equal." I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave-owners will be able to sit down together at a table of brotherhood. I have a dream that one day even the state of Mississippi, a desert state, sweltering with the heat of injustice and oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today.

I had one too terrible it was !! That one day when they introdiced the internet and placed this into public hands That all hell would errupt That the world would go bankrupt and that riotes and looting would start

Gosh fancy that I must have been seeing into the future !!

You can google: 100W Audio Amplifier project
which will give you many designs.
But if you have no idea how to start, I would suggest that you gain a knowledge of basic electronics first. A 100 Watt amplifier is a BIG project for a beginner.

By taking a bit of time to read up on the basics of electronics, you will progressively gain knowledge and ideas of what is possible, and soon be able to design and make circuits work (almost) the first time.
(Just like we all do (sometimes). ;-)

To obtain an understanding of electronics, the following sites offer free courses of instruction and advice for beginners. Have look at a few, and discover which one(s) suit your approach. Start with simple projects and work your way up.

We will always be here to offer the best advice and wisdom we can.
Many sites have a user forum for asking questions on any technical aspect.

Obviously does have an idea on how to start frank that obvious !!

Quote "this is very big circuit ( mic pre amp, head pre amp, pre driver, various type audio mixer, tone control, after tone cont driver, power amp and power supply circuits etc). can you build it by proper way "

In other words he knows exactly how to put this together otherwise he wouldn’t be mentioning
1: mic [re amp
2: head pre amp
3: pre driver
4: tone cont driver
5: mixer

In no uncertain terms he thinks you are stupid enough to put this altogether free of charge ,your time your investments ,your knowledge whilst he build this manufactures this and you wont get a penny from it whilst the likes of anyone stupid enough to do this on this scale sit-in shit hole , with every tom dick and Harry expecting you pay bills etc rents etc rates etc , never mind anything else whilst he reaps the rewards for doing sweat Fanny Adams
Probably haven’t done a stitch of work through his entire life time

Even manager who knows nothing at all working for a charity organization gets paid in excess of £25K a year Come off it wake up Frank

What’s is he on !! Hes not working for communist china buy any chance is he ??

Perhaps he thinks hes Mao Tse-tung " Shuttup or I punish"

If he wants to come up with an legally binding signed order for1000 60% up front I might be interested

Hasent heard this one iether has he "Money talks bulshit walks " in other words
Suck my ring piece pal
You kiss Uranus

On your bike
Go and teach your mother how to suck eggs
In your dreams

I can think of lot more but I dont want to be too rude not just yet anyway

I dont even do that for my best friends not that Ive got any Only time they ring me is when they want something and when theres a favour involved except for pne or four good pals who have stood by me

Cant say the same for the rest of them only to eager to stitch me up Even people Ive known for years and worked for loyaly as well who have always made money out of what Ive done even them Trade too" Filth the lot of them"

Mark, the enquirer said, "i have no idea how to start it," you are quoting one of the responses.

If he has no idea then how does he know how to break this down into operational blocks ? Exactly so he knows how to go about this then doesn’t he and there is the net which he can use to look each block up cant he

There you go but if you choose to believe that then you believe anything where as I know when someone is trying to take the Mickey out of people practically straight away and he’s a mickey taker

As I said you can do that for nothing if you want too I wont I may put projects up on this site for nothing but it isn’t for nothing if you think about this Its to attract customers and prospective clients who want something done and want someone to make that for them just the same as anyone else who advertises on this site They don’t do this for nothing

No one does The governments of countries don’t allow you to live for free They don’t even bury you for free


See below even China don’t do work for nothing You don’t work for nothing ,and no one else does, neither do people pay bills with nothing

That simple

Example one day ago advertising for work
PCB factory


Good idea as far I’m concerned I’ve no objection to this at all good luck to them that’s taking the initiative to build up on business and create work a dam site more than what the governments are doing at the moment or the unemployment offices

"We China pcb manufacturer want to expand our market in foreign countries, if you are interested in please visit our http://www.szbominelec.com and contact me"

Posted the other day I see “Manure Groot beck Collin” , hasn’t said anything at all Wonder why that is then ?? Could he be he has a side deal going on with them or has seen a cheap short cut to what he wants done Aaaah !!

Finally Frank there is an old age saying which is just so true you know

"You pay peanuts or next to nothing or nothing you get monkey’s” And boy have you got some monkey's in business these days Hence your poor economy and one business going bankrupt after another must be because they pay nothing or expect everything for nothing

well, that escalated quickly. http://images2.wikia.nocookie.net/__cb2013042...t/images/5/56/Well_that_escalated_quickly.jpg
