Hmmpf. I see we've been relegated to the miscellaneous forum. Leitz projectors thrown in with the bags and cable releases.
I use Ektagraphic projectors, and recently picked up a Leitz RT-300. I also use Hasselblad PCP-80.
I got the Leitz RT-300 after reading a few posts around cyberspace, that it has a whiter light than the Kodak projectors. It uses a dichroic mirror rather than the greenish heat absorbing filter of Carousels, Ektagraphics, and most others. I'm finding that when I do a two-projector dissolve show, with one RT-300 and one Ektagraphic, I don't notice any difference in color cast between them, as the two machines alternate. So maybe it's not a big deal.
The RT-300 runs a little quieter than some of my old Ektagraphics, that like to rattle and clatter. That's good. Two or three of my Ektagraphics (I have six) are just as quiet as the RT-300. I can change a lamp in the RT-300 from behind the projector, without having to flip it upside down or disturb its alignment. That's good. The projection lens has to be inserted into a tunnel. This makes it hard to use my Schneider PC lenses, and impossible to use my large Golden Navitar lenses. That's bad. The RT-300 is larger and bulkier than my Ektagraphics. If I were to switch to all RT-300, I'd build new stands for them, or modify the ones I already built.
Any comments from other RT-300 or Ektagraphic users?
