Well, as it's a P FET I was thinking upside down, but evidently not thinkin=
g
hard enough and it's come out as part N FET drive

I've restored the circuit to how it originally was

Output is 2.2V into 6R8

Gate voltage is from 1.3V to 8.8V. The test circuit in the ATP106 d/s
shows gate drive from 0V to -10V, with source at 0V, which would be
0 to +10 for an N FET. As I figure it then, my gate is reaching only a
relative -7.5V

So I should be taking the emitter of the BC327 to at least a couple of
volts below 0V if source is at +9V ? That would make the gate 11V
below the source
