macdaddy posted:CW, yes I did see that post. I could go with the HH Smith single banana plug for the one set of leads but I am still trying to track down the double banana plug for the 5D and 5F. The center to center of the holes is slightly larger to that of the 5C.
I have also noted that Lionel seemed to re-use the instruction manuals from the 5D for the 5F with some modifications. Notice the meters on the picture diagram with the curved tops.
What is the exact center-to-center spacing of the dual banana plugs you need? Do you have a photo of an original one?
