Kind of out of the blue (one gig to the next), my old Altman Dyna-Spot started projecting the vertical bulb filaments. The layout of the spotlight is back reflector, 1000w bulb with filament rows running side to side (flat to lens), a multi-ringed lens, iris, fixed focus(?) lens, then the adjustable focus lens. Has one of my fixed lenses moved on the positioning rails? I already tried a new bulb. Any advise or knowledge?
