2.5W * 2 Stereo Amplifier

Comment by ModifiedLife on January 14th, Comment by Justin on August 24th, What I would like to do is build a dual power supply that will send 15v to the pre-amp and 12vac to the power amp. DC voltage can be connected. Also, I may have trou.

But if you want more power, check the datasheet for how to connect the outputs in mono-setting. I need to boost a signal sixfold before I divide it by 6 to send to 6 different destinations. Can this be done with an LM? Also, I do not seem to be able to make the LM specs give me hints on how to do it. The amplification part should be possible yes. Check out page 5 in the datasheet for circuit examples: For splitting the signal, you can use resistors for basic splitting.

Hello, I am facing a strange problem with this circuit. I am powering this circuit 12v just so you know. When I was tinkering with the circuit, I found that removing the uF capacitor connected to non working speaker and shorting the wire, the speaker starts receiving sound but now the output is way too noisy.

I tried replacing the capacitor but nothing happened. Do you have any idea? Thanks sir you are really doing, but I plead your indulgence to ask you of how to build a W stereo power amplifier. You can find one here: Hy guys my problem is i dont know where to buy those printed circuit boards i live at durban.

This is a really cool thing! I am new to electronics so I have a stupid question. How can I connect the two inputs to my laptop if I build this on a breadboard? Hey Kirk, You need to use an audio mini jack to plug into your laptop. Mini jack on one side, loose wires on the other side to plug into your breadboard. Thank you so much for the reply! Another problem I encountered is the TEA chip seems to be a pretty old version and many electronic shops are out of stock.

Could you tell me where I can buy it since I wanna start building it in a week? I found various completed circuits out of hi-fi systems and portable radios.

Im trying to use them all in my car as a complete built in system, without using a radio that can easily be stolen. I have wireless bluetooth speakers that came with my phone that i want to put front in-dash, a TEAD circuit from an old treadmill and a TEA that i got from an old hi-fi. Im only using my phone as the music player. When i connect the one with the other, a lot of sound disipates or alot of static comes through, giving me the idea that one or the other is getting too much power or drawing too much.

Please give me some advice. Youre welcome to have a good long laugh at my expence first, but my reasons for this idea is not to spend any money on the system and still get powerfull sound, while making sure nobody is tempted to break into my car when they see a radio in the dash. FYI, ive lost 4 radios in 3 months through crime and im done buying new radios.

Pls my problem is with the schematic, Between C5 and C11 you made C6 to pin 15 pass through. Same thing applies to C7, C12 and C8. The question is; are they interconnected on those points. Thanks for your effort. Yes they are all connected. If you look closely there is a little dot where they all intersect. This dot means that they should be connected. Thanks for your help. Pls help me with the schematic or circuit. I enjoy seeing constructed circuits. Nice and useful post. It is a good circuit for amplifier, but you have not mentioned the voltage of capacitors Polarized from C1 to C8.

Please mentioned voltage of capacitors to make the circuit useful for beginners…. I am not a HiFi […]. It is basically a map. Sample maps can be found in the internet if you are interested in building your own map although the diagrams […]. Your email address will not be published. Notify me of follow-up comments by email.

Check out the TEA datasheet for more information on that On the input side, you should use a dual potentiometer. Comments Hello Oyvind, Thanks for this useful post. Maybe your old speakers just had too low Watt-rating… Anyway, great that you got it working! Hi, I challenge you to figure it out from the datasheet: Why Do We Use Capacitors in this circuit..

Hey, yes that should work fine. Hey, Check the datasheet of your potentiometer to find out the pin configuration, then match that with the diagram above. Where would I be able to order the 0. Hi, For example from Jameco: Hi Andy, If the sound is very low, you can try to increase the volume of your input device.

Hey, I think it will become a bit hot yes. But not more than it can handle. Yeah, it is pretty good, right? Is the layout drsignes to be used with a double sided copper board.? Hey, The design I created was double-sided. How much voltage rating should have uf capacitor for this circuit. Can i use 25v capacitor??? Yes, 25V should be fine I think. And yes, single-sided pcb works fine. Why u was use soo many cap in circuit…..??

Hello Oyvind, Thanks for this website. Hi, Well, I guess this article is a start. If I want to make it Mono, I ignore one of the inputs? Clearly I need to learn how to read a spec sheet. If you need exactly 6, you can play a round with the resistance on the input. Check the sound level of your music source. How can I buy your textbook sir, for I really neef it.

I wanna make an amplifier use for 6 spkr.. Is there a way i can link them up together? Hope you can help Thank you. Hi, Yes they are all connected. I just want to know what is input and output there before potentiometer? What I would like to do is build a dual power supply that will send 15v to the pre-amp and 12vac to the power amp. Not to mention the smell.

So If anyone has any bright ideas, precautions and next step learning, please drop me an email or something. You would be doing my whole Apt. Hi, i hope you worked this out. Hi Wayne, that is actually a very smart suggestion. However, I only recommend it to those who understand the concept. Mixing up the positive and negative terminals have disastrous results when not done right the first try. The filter caps are fine rated for 25V. Maybe with a lower voltage input like phono preamp output you might want the full gain as on the specs.

Hi Just bougt an readymade amp from china using this excact layout. Do I use a stereo source? Or do I have to mix it to a mono before? If I mono it first, where do I input the signal? You can feed it stereo, but 1 channel is now disconnected leaving you with mono audio. Depending on the music you must mix it to mono first. What is the transformer requirements for This circuit? Hi I built this. Due to the high current peaks a current rating of 2A is required.

I used a 3A TX as I had it in stock. In a solid case the amp sounds very good. I found uF 35V degC from maplin. Can I bridge this version the same way ,by omiting the c9 and Building the board without it?

Initaily I wanted to use the 2 boards bridged ,Any thing I can do to doing it. Ok, I will store these boards,until I learn more about parralell bridgeing. I fell in love with the sound of the A I want to build a nice powerful example of one and something says to go this route. Hi, people, great thread here! Just wondered if you would recommend this transformer for the above ebay kit? However, I am not sure if the sound image quality will change because of the different characteristics between the electrolytic and film capacitors.

I bought this board 1. I soldered tha parts month ago, but i wasnt statisfied with the sound quality. I put it into a box, and have totally forgotten. I connect this amp board to 12V AC, everything ok.. The voltage of cap which is directly connected to negative gets higher, the voltage of cap which is directly connected to positive gets lower..

If i break the the supply for a while everything will be ok for few seconds. If i connect DC 12V to the caps, the symptoms are the same. Does anyone have any idea how i can solve this problem? Happened to me also. In this case the sound quality is perfect.. D i bought an NE timer, because i wanted to learn and see how it works, and if i interrupts the power supply it works.. But i think its not normal behaviour.

Have a look at the schematic on this page. It sounds like you connected a 2 wire transformer to the amplifier. If that is the case, you need another transformer with 3 wires. You then connect the center tap 0V to GND. The other 2 into each AC input. I found an old 12V AC transformer and connected it directly.. Thank you so much for discovering optional resistor R4. It helped me to understand what was wrong with this amplifier!

I have just recently bought two of these amps and am having the same problem, I have googled extensively for a solution and have had no luck. Hi Peter, have a look at the first picture. There are markings on the pcb that tell what should be connected. Yes, that is correct. Never seen so much information anywhere on the website. I also use them for experimenting. They are cheap, but the transformer raises the price. Is there any way to find the current ratings for the transformers?

How much per one TDAA? Also, is it possible to remove the potentiometer and set a fixed voltage? I also suppose the dimensions are loose, but it must be larger than a paper clip and smaller than a tin can, but how about a ball park figure?

Also, I may have trou. Hi Richard, take any cpu cooling block, it will work just fine. Also, you paperclip cooler will also word, only on low volume. Continuation of previous comment, lost in my crude typing skills. I may have trouble finding adapters from my input devices to the input jacks. Any suggestions on a source, since Radio Shack bit the dust? Thanx for the info, guys. Could you be more specific as to the actual connection points to apply DC power in this circuit? Also, is the output from a microphone or a guitar pickup adequate to apply to this amplifier?

Thanks for helping this out-of-date tinkerer.
