It Is suggested that if you have a 40W stereo that ou should use o 10 K resistor. e smaller wattage stereo use a bigger resistance. The resistance should really be based on the le wattage may be way off. The resistance value Is not critical and not really needed. If you our stereo way down before switching from the radlo, tape, etc. to this sound board the line Inputs on most ampliflers. Domage to your stereo may result If you plug the outputs Installed between both devices. t find a K$555 you can use an LM555 or other equivalent. stitute other types of logic for the 74HCT chips.
