Finally got home, and it's beautiful! Just one question - what are the included red and black plastic thingies? The driver space is relatively large, just not sure what those are for. I think they are related to the driver?
Good question. The "screw caps" were included because I had so many left over from the first run of grooves. They were initially intended to be an aperture cap, to prevent accidental beam shots.
You can use the parts in teh driver chamber to prevent shorting of the driver spring to the side of the unit.
ignore the numbers..
Or you can use them for what they were DESIGNED FOR, which is a screw cap.
