I was given the job of designing an amplifier, there are not many constrictions other than the rail voltages (+/- 13.8 V) and load impedance (8 Ohms). I've spent hours trying to design this thing and am having trouble. I believe that the 2nd and 3rd stages of my amp are working fine but the differential stage not only inverts the signal, but it is also de-amplifying the signal instead of amplifying. The schematic that I am having trouble with is attached, any hints or suggestions would help.
Thanks!
Thanks!
