Hey.
I just built a clone of the xotic ac booster, and used a millenium 2 bypass for the led.
The led shines nice and brightly when the effect is on.
When I switch it off, the light intensity decreases drasticly, BUT the led is still shining.
I'm using a BS170 (fairchild I think), 2n3904 and 1n914.
I built a zendrive about a week ago, and used the same layout and components, that one works fine.
I read about the millenium 1 having this problem, but this is version 2 with the mosfet....?
Anyone got an idea what's wrong?
