In Reply to: Bridging a Soundcraftsman amp posted by webgeek on March 8, 2002 at 08:13:47:
Probably a inverting and non inverting -preamplifier that gives you two signals out of phase with one another. One signal feeds the left and the other feeds the right channels. The output is then fed balanced with respect to ground. Two hot speaker leads + and - each signal 180 degrees out of phase. This will double the power output and double the slew rate of the amp. Don't try and drive a speaker less than 8 ohms however or your asking for your amp to become an arc welder if any DC offsets pass through your amp! There have been construction projects. Audio in about 1979 featured an AMP STRAPPING CIRCUIT by Marshal Leach of Georgia Tech. He still teaches at Ga Tech and has a web page. Good luck! Soldier of fortune James
