Hello all!
I am looking for a dual banana plug connector to match the socket on a Leitz microscope from the late 1960s. The individual plugs are somewhere around 2.5 mm to 3 mm diameter and about 12 mm long. The spacing between the plugs is about 13 mm. All I need is the plug, not the socket. If a dual plug is unavailable, I can use two single plugs that fit.
These are used to connect illuminating lamps to a two-output variable supply (up to 8 V 0.6 A each) in the base of the microscope. Currently, one output is used for the main illumination, and the other output is unused. The second output was designed for an optional illuminator for a scale in the eyepiece, which is probably unobtainium now. Currently the user is simply shining a flashlight into the window where the optional illuminator would have gone, but I'd like to create an "integrated" solution with a small lamp or LED for the scale illumination.
This connector is exactly the same idea as the 0.75"-spacing dual banana plug found on much US test equipment, but smaller. Digging around on conrad.de , I find 2.6 mm diameter single banana plugs. The diameter is probably right, but the plug seems a little short at maybe 8 mm.
Any tips or leads will be appreciated. Thanks!
