I got an absurd deal on a half dozen virtually unused Lee Colortran 6" Fresnels Model 213-515.
They look very similar to the Strand Fresnelite, except instead of a lever at the back to adjust focus, there is a non-locking knob on on the side that drives a gear. It is under slight tension so it holds whatever position it is set to.
On one of them, the focus knob won't hold focus. It doesn't have the same tension as the working ones, and gravity is enough that the knob will spin as the sled holding the lamp base and reflector drops to the full flood position.
Has anyone had the same experience with these and can save me taking apart a working and the non-working one to figure it out? Or a digital copy of a parts diagram?
