Audio Stereo Amplifier KitThis kit will teach you how amplifiers take a small signal and amplify it to drive two small speakers or headphones. It is based on two LM386 ICs and one LM1458 IC. The LM386 chip is not a toy, for it is designed to be used in a variety of consumer electronics applications like AM/FM radio amplifiers, portable tape or CD players, intercoms, TV sound systes, and more. The kit provides up to 1 watt of low-distortion audio power. Harmonic distortion is 0.2% with a voltage gain up to 46dB. You supply the speakers/headset and input power source. Features: Output Power: 1 Watt Power Requirement: 7 to 15 VDC, well filtered and regulated. PC Board size: 2.25" x 2.75"NOTE: The 9V battery snap shown in the image above is not included. Input power must be well-filtered and regulated and should be between 7 and 15 VDC, but 9V DC is recommended, especially if you are using this with other kits from Rainbowkits.Kit Includes:Part No.Qty.Description R2, R1121K ohm resistor (brown, black, red) R7, R12210K ohm resistor (brown, black, orange) (use with mic only) R3, R8251K ohm resistor (green, brown, orange) R4, R52100K ohm resistor (brown, black, yellow) R6, R92270 ohm resistor (red, violet, brown) R1, R10210K or 5K trim pot (horizontal) C2, C324.7AmicroF or 10AmicroF capacitor C7, C8, C11, C124Optional capacitors (see text) (customer supplied) C1, C4, C6, C940.1AmicroF capacitor (marked .1 or 104) C5, C10247AmicroF capacitor U2, U32LM386 audio output IC U11LM1458 IC U1S, U2S, U3S38-pin IC sockets Pins12Connecting terminals PCB1#080-00368A Check out more fun and exciting electronic kits
