D Condenser Lamphouse - non-filter model

All the D series lamphouses consist of three sections - the light cap that has the lamp socket, the main body with the mounting points, and the condenser assembly. The differences between the lamphouses essentially are all to do with the main body assembly. All D series lamphouses since 1941 have used the same 6½" standard condenser set.

This is the basic double condenser lamphouse that was standard for DII, and initially for the D2 and D3 enlargers. As can be seen, there is no provision for filters. For formats other than 4x5, the user was required to install accessory condenser sets to match the focal length of the lens being used. Three additional sets were originally offered - 5", 4½", and 3½". Later, a 4¹¹/16" set replaced the 5" and 4½" sets.

Used Advice: Anyone encountering this type of lamphouse should first check that the auxiliary condenser sets are included. If not, rather than attempting to track down missing condenser sets, it's better to install a DV conversion kit, which will provide both the more convenient variable condenser configuration as well as a filter drawer.
