Tom, the CRT is only visible under darkness and it is a darkish blue scan with a bit of retrace going on. UV I suspect. It would have to be a big LED array to do the same. If the lid is open to light, you get white streaking across the frame from the room lights in to the PMT's. The PMT's have no markings on them and the manual only gives Moto part #'s and they are tight in the sockets so I will not force for now.. Unknown for now. Dude, photos below in two posts for all nine photos.

1 - Full unit cleaned up. Reel goes under black lid.
2 - Play, still and track select controls. There are different versions.
3 - Supply reel platter. Leader threads CCW in to a slot in the UR of the box.
4 - Take up reel with all optics visible. CRT is under shroud aimed at A/B
lenses. Lenses see both tracks at one time and divide them to PMT's
5 - Shroud off to show CRT and lenses. Triangular item covers light divider
guides to each PMT. One for A, one for B. Not sure if divider is glass
or acrylic. Magnetic audio head is out of sight.


More to come.
