I'm in need of a C-1 RCA narrow slit len (0.59 mil)
or C-12 RCA narrow slit lens (0.47 mil). The PS-2 sound head
I currently use has an old slit lens that picks up the dts track when on the film. Adjusting has not helped. The light slit is too wide. Also the newer slit lens will improve high frequency tones. A new one is very very expensive. Out of my limited reach. Hoping someone has one laying around cheap. Anyone replace a optical system lately?
