Thanks for the link. The first post says it's the same except with 5 mm LEDs, a 2M2 gate resistor, and another 2M2 resistor between Gate and Drain. But then the second post says thr only change is the LEDs. So it's still not really clear to me.
If a Turbo is just a regular with 5 mm LEDs, then I guess I'd just do the old 3 way diode switch mod and have both options available.
