Step 7: Finally Done ^_^

okay just stay together all parts !!!

this amplifier use two way power :
1. 9volt connection for 9volt baterry ( low Quality Output )
2. Power Jack for 12 volt - 18 volt input ( for better Quality Output )

OK , hopefully this can inspire you 

Thank You

<p>Hello and thx!<br><br>I am new to electronics yet i managed to build this amp and its working properly.<br>I must say thought that your schematics are totaly different values than the ones you used (showed in the pictures). Some values are not shown at all some other are misplaced. For example C2 = 1000uf (taken from your images). In the schematics thought you mention C2 as 470uf. </p><p>and Goes on.</p><p>C1 is 470uf and in schematics you say it is 2.2uf.<br><br>Please correct the numbers in schematics so we all know what you really did here.</p><p>Thanks alot for your project it was nice!</p>
hi,i wanted to know how a 2.1channel system produce 5000watts using tda2030.The subwoofer box is ported plus sealed.There are two satelite speakers,-12,0,+12 transformer and jrc4558 ic.
can i use a 4 ohm speaker?
Hmm not bad it worked (high five to you sir .
<p>Very nice instructable. i only have 1 point of improvement. namely the Cx.</p><p>Cx's role is that of a high-pass filter. High-frequency goes trough it to the inverted input of the amp resulting in Treble-Treble=nothing kind of effect (upper frequency limit). 33nf is ok for high-frequency AC testing, but with audio the filter is far too small letting even noise trough and giving the high pitched sounds a almost shriekish sharp end as you become unable to hear it. instead you would want to limit the frequency to be near hearing so it rolls off the treble giving a far greater sounding sound (and little to no noise!)</p><p>I myself have settled to using a tiny 4.7uf cap (Positive towards the amp output). It cuts of the frequency just below hearing limit and removes almost all noise i had before. it upgraded my amp from sounding nice to sounding like a classic HiFi speaker.</p><p>I big thing i always keep reminding people of is to experiment with these kind of circuits. try different cap vallues and such. oh and if able use metal-film resistors. they do a far greater work then then the generic brown resistors and aren't costly at all.</p>
<p>making circuit on proto board. um where does the pot go in the circuit, not noted in diagram</p>
<p>Ah the potmeter is the Volume control. idea is that 1 connection is to the audio source. the other to ground and the wiper (middle) to the Input of the diagram.</p><p>Oh if feeling adventurous play around with the vallue of Cx once you got it working. You can alter the audio quality quite effectively trough it as the one used by most isnt exactly the best. i prefer replacing it with a 10uf cap.</p><p>Hope this helps.</p>
gan sorry itu diskema nya letak potentio meter nya gk ada potentio meternya ditaruh di output atau input thank gan cuma itu aja bagus karyanya
<p>hi bro, for the potensio you can add it at the input of the IC..</p>
thank bro and good and nice job
Can i use tda2030?
<p>each ICs have different how to use them, to make sure it, you must see the datasheet and make some experiments </p>
Nice design
wt abt output den? <br>
Ooopsss , I am sorry, man .... <br>j9 is for output (loudspeaker) <br> <br>j6 is for power input , it has 2 ways : 9v batery (using 9v connector) and adaptor ( using Female jack connector) . They are paralel .
wats j7,j6 n j9??
j7 for input audio <br>j6 for input batery 9 volt <br>j9 for input 9 - 18 volt <br> <br>Here is it , hope can help you : <br>========================================== <br>The Layout : <br> <br>https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-prn2/8655_586240588064840_562823952_n.jpg <br>========================================== <br>The Schematic : <br> <br>https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-frc3/501_586240574731508_970148564_n.jpg <br>========================================== <br>The 3D : <br> <br>https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-ash3/q71/s720x720/1011909_589421264413439_499067393_n.jpg <br> <br>https://fbcdn-sphotos-e-a.akamaihd.net/hphotos-ak-ash4/q71/998252_589421254413440_570515331_n.jpg
yup got it! <br>
thnx man
i need the values for evry symbols pls ???
hey.wat does dose j1 j2 j3 j4 c1 c2 nd ol stand for..........???? help pls...am in really need of dis <br>
j1 j2 j3 j4 j5 is pin of IC tda2003 <br>C mean Capacitor , the value of c1 is 100nF(no polarity) and the value of c2 is 1000uF
value of potentio meter ????????????
stil confusin! <br>nyways how much value does the pot hav? <br> <br>
for the value each component you can look at the schematic picture
man.........i jst created a new account for myself bcuz of ur dis project......i really need help...can i c snaps of d pcb with ol d solderings nd connections..close up...am a 16 year old boy frm india...i need an understandable schematic circuit diagram? can u? help me pls?
Here is it , hope can help you : <br>========================================== <br>https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-prn2/8655_586240588064840_562823952_n.jpg <br>========================================== <br>https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-frc3/501_586240574731508_970148564_n.jpg
beli akrilik yg kaya gitu dimana ya?
Acrilicnya saya potong sendiri gan trus nge-lem sendiri juga , hehe...
ok, so you said a 12 volt would make this sound better. it sounds interesting but I would need some help, for the power, do you think I could just use a DC wall wart? or would it have to be AC? (sorry if this is confusing, im kind of new to electronics, i've only been working with them for about a year now) and this project seems like a great idea since I love working with speakers and I always get lots of request to build some for people! (i've gotten a request for a mini ipod speaker for $20!)
Can you please tag which capacitor and resistor are which?? I really want to make this however I can't work out where each resistor and capactior go, and how many of each I need. Good instructable otherwise :)
Terima kasih NatDaGamer ^_^ <br /> <br />Please check this <br />
What resistance potentiometer should i put? 10Kohm or 40Kohm?<br>Also i seem to have a problem with huge distortions on low volumes. Could it be because of the potentiometer being 10kohm?
Nvm solved it. For anyone wondering i had 2 4ohm speakers wired in paralel. I fixed the distortions by connecting them in series.
layout is on What?programma<br>
layaut is on what programm
Also that what are Cx and Rx for in the datasheet ? there is no description of the circuit do you have any link ?<br>
nice instructable and easy to build too but i have few questions<br><br> can someone help me i built it but the output was distorted not too much but it was enough to annoy some one (when the output is at max volume) at lower volume its fine enough.<br>CONVERSELY<br> and when i short the capacitor C2(1000uF) the output gets stable and distortion is reduced (at max volume) but gets distorted at lower volume .<br>strange but true <br>anyone who has built it can try himself and what is the solution for low distortion at max and min volume simultaneously.
can you modify it to run on 12 volts or does it need 18 volts because i would like to use it on a robot that only uses 12 volts also what is the maximum wattage it can run
12volt supllay is fine ^_^
what is the largest speaker you can run (:<br>
I appreciate your modularity, use of standard connectors, power, simplicity, and portability. That is really quite an excellent build.
Thx ^_^
wah, joss tenan dap, wong indonesia iso melbu newsletter, HIDUP INDONESIA
Saya juga kgk nyangka gan ,, hehehe ^_^
i have a... maybe stupd question... is it posible to put 2 or more of those in a row?<br>
I suggest you to build a stereo amplifier , it is more efective and efesien
hey bro.. can u upload your pcb layout?<br>
Yes No Problem<br>http://www.ziddu.com/download/17590310/10wattamplifier.rar.html
