C760 Diffusion and Vari/Con Lamphouses

These two heads are identical, only differing in that a variable contrast filter module was included with the Vari/Con. Intended to provide a convenient diffusion lamphouse for black and white printing, they were based on the C760 Dichroic lamphouse and used the same quartz-halogen lamp and mixing chambers.

The variable contrast filter module used dichroic yellow and magenta filters mounted with an attenuator in a small frame which fit in the slot on top of the lamphouse. The filter was calibrated for both Kodak Polycontrast and Ilford Multigrade papers. By raising or lowering the filter slide, the user had continuously variable filtration.

In addition to fitting the C760, they came with a bracket for mounting on C-700 and B600 enlargers, and adapter kits were available for mounting on the B-66, B-22, and C-67 enlargers.

Used Advice: Since they are based on the C760 Dichroic head which is still current, these units can be easily serviced, but the variable contrast filter module is no longer available. As with the dichroic lamphouse, used units should be examined for physical damage, particularly the styrofoam mixing chambers.
