Projection box circa 1971 showing 2 x Kalee 21 35mm projectors (optical only) with Autoarc carbon arcs, and recently acquired Eki 16mm projector (optical & mag) with Zennon arc lamp. Previously the 16mm projector was an old B&H projector (609 I thin from memory) with an auto arc run off two B&H rectifiers in parallel. You just had to remember to switch both rectifiers on to together to avoid “current” overload.
