2¼"x2¼" Enlargers

Introduced: 1977
Discontinued: 1980

The B600 and Chromega B600 enlargers were used as the basis for a series of specialty enlargers called Concept Six. Instead of the usual baseboards, these enlargers had a special "structural foam molded" base incorporating a borderless 11"x14" easel and either a paper safe or exposure meter/timer combination. 

The CS-25 model incorporated a reflected light, integrated reading probe and timer combination, while the CS-50 used a spot reading probe, had a wider timing range and could also be used for contrast measurements.

The Concept Six enlargers overlapped the B600 and C700 enlargers, so were sold with both types of lamphouses.

Used Advice: Since the Concept Six enlargers have so many chassis parts in common with the C700, the enlargers themselves can still be fully refurbished without problem.  However, the timer/exposure meters are not likely to be worth servicing as the probes and many other parts are no longer available.
