Here the schematic diagram of 6-10W stereo power audio amplifier:
Component list:
R1, R9 ________ 1K ohm R2 ____________ 120K ohm R3, R4 ________ 1K2 ohm R5, R6 ________ 33 ohm R7, R8 ________ 1 ohm IC ____________ TDA2005 Pot ___________ 10K ohm stereo | C1 C2 __________ 2u2/50V C3 _____________ 10uF/25V C5, C6, C8 _____ 100uF/25V C7, C9 _________ 220uF/25V C12, C13 _______ 2200uF/16V C4 _____________ 100nF C10, C11 _______ 100nF |
This is stereo audio amplifier which use dual IC TDA2005, one IC for left channel and the another one for right channel. Each IC will give you 20 watt output, so the output will be 2×20 Watt.
