Schematic + demo from a 1 transistor audio pre amp that aligns volume, high & low frequencies, loudness and (overall) amplification.
For stereo you have to make it twice.



Much more info and schematics about audio circuits in my book "Schematics 2, audio amplifiers and loudspeaker boxes" available on the LULU website, search for author Ko Tilman.

All my videos about electronics are visiblie via my channel trailer "Radiofun232 on You Tube"" (the videos are indexed thematically).
