HFA3096 transistor array breakdown voltage
Your actual question has been answered in the comments, but I'm going to go ahead and do so here, and list some suggestions for fixes.

Answer: that circuit violates the transistor's breakdown voltages.  

Suggestions:


You could fix that by dropping the supply voltages to \$\pm\$6V or so.
The 100\$\Omega\$ resistors force an awful lot of matching on the transistors.  That input stage would probably be mostly OK with randomly-chosen small-signal transistors, even ones that came from some surplus house's grab-bag.
That circuit doesn't need a bunch of matched transistors -- it just needs a matched pair.  I checked on DigiKey, and got back a bunch of hits.  There appear to be at least four different part numbers for NPN matched pairs, and at least a hint of PNP matched pairs.  If you understand which pairs transistors need to come in matched pairs and which don't, then you can do your discrete op-amp design without using that specific chip (which was getting hard to find when I was the IEEE store manager for Portland State University back in the mid 1980's).
