hello I am unable to get the folowing cirucit to function corectly.. I think it should have a difirential gain of 2 but I have made a design error I think. Can anyone help out?

I presume the problem is how I have implimented the feedback as the same amplifer when operating with a current mirror load for the difirential pair and the output fed into the inverting input resulted in unity gain (and quite high slew rates).
I'm trying to produce a single rail supply lo gain amplifier with no capacitive coupling for use with low offset sources such as my soundcard.
