Talking to the guy in the next cube, the NPN-NPN design of the G08
will have a problem with inductive kick in one direction that the
PNP/NPN designs won't have.
He also thought that the relatively low voltage ratings of the
3716/19 might make this a problem for the WG as well.
The other thing he was wondering if you only drove the output
transistors from the unregulated supply or the diff amp and
pre driver as well. If the negative rail isn't well regulated
in the diff amp, you are going to inject a whole bunch of noise
through the current source.
