Hello Oyvind, Thanks for this website. You can also make a 5W mono amplifier out of it. Another problem I encountered is the TEA chip seems to be a pretty old version and many electronic shops are out 45588d stock.

Should I just use a mono amplifier with similar specs as the tea? Probably a dual op amp: Hy guys my problem is i dont know where to buy those printed circuit boards i live at durban.

Can i use 25v capacitor??? Comments Hello Oyvind, Thanks for datashet useful post.

Are the potentiometers needs to be a Dual Potentiometer 6 pins or can I use 3 pin potentiometer? How can I buy your textbook sir, for Datashret really neef it. I use to make amplifiers from the internet and it makes little hmmm noise when the volume is attached. If the input signal is too high, you will get clipping on the output. Try switching the inputs and see if this gives you an output on the other channel.


Is the layout drsignes to be used with a double sided copper board.? Hi, Yes they are all connected.

Buy a tablet power supply 5V 2A, for fast charging and check current consumption with a multimeter. Hi, The incoming signal could be too high. Home About Blog Contact. Hi, I challenge you to figure it out from the datasheet: You can also combine capacitors in parallel or series to get other values: What is the function of TR1 in this circuit 3.

Hey, thanks for the great schematic, I was actually looking to make an audio amp and this one looks awesome! It was always something that made me hesitate. Trackbacks […] TEA — 2. If you love building things with electronics or would love tocheck out Ohmify. Could you tell me where I can buy it since I wanna start building it in a week? Can this be done with an LM? You can find this info in the datasheet of the TEA chip: Not sure what pin that is, but check the datasheet and you will find info on all pins: Well, I guess this article is a start.


Also, can you help me with the Potentiometer? 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. I have purchased W sterio amplifier with USB and mic-2 kit i want to understand bass treble and volume wiring in 6-pin pot. Distorted Sine output from Transformer 8.
