Wow, a differential amplifier circuit! It is relatively easy to figure out the formulae for finding the DC currents, AC gain and all when the an emitter resistor and a negative voltage bias source are used. But when a constant current source is added, things get way more complicated. Check out this similar circuit which I am struggling to find the formula for AC gain:- http://everycircuit.com/circuit/6531676140994560.
