That's good to know. When powered up the green light on the left goes on
and the red button/light doesn't do anything. I took the bronze cover off
and the tape is attached to the leader grabber thingy but hasn't yet made a
wrap around the hub.

I didn't try it "three or so" times, I did push the button in, and then
push it again to leave it out and nothing seemed to happen. To be honest
though if it blinked for just a second i wouldn't have seen it. I'm going
to look carefully at the capstan roller to see if it is turnable.
