We bought this slide projector new for home use. We eventually bought a
second projector, a Kodak Ektagraphic E-2, so we could develop
background slides to go with Brenda's songs she sang at various
churches. We also bought a projector stand to stack up to
three projectors and a dissolver unit to fade slides out from one
projector and in from the other for a smooth transition. Using a reel-to-reel tape
recorder, we would record the music track on one channel and then record
the dissolver signal on the other channel by manually running the unit
during the recording session. It would normally take several tries
to get it right. But once we did, all we had to do was play the tape for
the music and to run the slide projectors automatically. It worked
well. The problem was hauling all that equipment around from
church to church and getting it lined up and ready to go. Today's
digital world is a lot easier and cheaper. This projector was
refurbished in 2012 and works today.
