Must be a good thing.

As near as I can see the Quad II uses an ordinary paraphase phase
inverter, not a "floating paraphase" phase inverter? I also can't see any
large use of positive feedback in the Quad IIcircuit. I see a very small
incidental amount of positive feedback that appears to be a side effect of
the way the loop feedback is connected.
