Does anyone know what the external gate minimum voltage is on the SL? Is +5V enough?

If you're 100% sure then don't hesitate to correct me. But I'm about 98% sure that: -
You only need to turn on Q8. The drop across D7 will be 1V(4148) or less and the drop across the B-E junction of Q8 would be .7V so I think 2V should do it.
