I have decided on this design and tweaked the rails to 9V and 3V,

To begin my project, I also need a PNP version that will run form -9V
and -3V rails. IOW swing between -8V and -3V.
I have played around with the components in LTSpice, but without much
luck. There is nothing I can find on the net to work from.
Can anyone please set me on the right track regarding what changes
need to be made?

From a thread on S.E.D:
I opted to use fewer supplies, and invert the signal to allow simple
accrual of more loop gain.

I love to cook with wine. Sometimes I even put it in the food.
