h : )
instead of wiring up the power on the schematic , i placed red and green dots , just to show where power needs to go. because i cant figure out how to make a them connect without ground problems
i can make the op amp work. the line driver work, and the VU work . they all work.
but when i put them together, the dual rail power does not want to work with the single rail ( the regulators)
i have a 12v and a 5v regulator in the project box. the line driver needs dual rail , so i create a flaoting ground type of circuit, but the grounds of the flaoting ground and the regulators cause problems together.
I have also tried powering the op amp and the line driver with a dual rail floating ground, that worked o.k , but when i added the VU circuit there were problems a soon as i connected the ground.
pheww. not sure what to do? maybe create another flaoting ground circuit for the VU IC.? so that all the IC's have a floating ground?
