K Kid Twist New Member Jun 22, 2009 #1 Hello! As my first electronics project, I am trying to build a small audio amplifier using the "TDA 2822M" ic. I am using this stereo schematic from the datasheet: **broken link removed** My question is: where should I connect the negative voltage? Thanks in advance for any help!
