You learned how to simply solder parts together.any concept or main point for the circuit ? and how it function , transistor work for , why signal cabal connect from collector of transistor but not emiter or base?
C7 and C7 filter the battery or power supply voltage so it doesn't bounce up and down with the audio. C6 stops the audio amplifier IC from oscillating at a high frequency.how about C2, C6, C7?
how about the transistor ? why the audio signal transfer from collector and not the emiter ?
