2 100k potentiometer resistors and capacitors with a simple inexpensive quite well that works a tone control circuit bass and treble controls are doing RC low-pass filter the low-frequency bass sounds RC high-pass filter section treble passes
With this state of the circuit can be used for mono signals only for two-channel stereo dual stereo 2x potency can use other materials, then increases
Best of all transactions done on the direct sound does not have to supply any need to use a power supply. Check-section mp3/mp4 player cd player, low level audio output devices which can connect you to the entrance will connect the amp to the output section
Simple Tone Control Circuit Test
The video is not very clear voice but the voice is very clear impact on small video sonuna I just add the audio recording that was more pronounced

PIC16F877 Digital Logic Integrated Test TTL IC Tester Circuit
EPE magazine free distribute a project is actually a previous post could be added, but I want to isolate because too different circuit digital logic ICs with that circuit will test you can install on your computer that you program with visual tested as integrated data can be seen
Circuit PIC16F877 based on computer communication MAX232 RS232 port provided for connection ZIF socket, thanks in different sizes integrated, can be tested source asm and hex software’s test phase circuit operating principle and explains in detail (english) also cable Shamash is in
