[Test-Equipment] GR 1800A VTVM

[Barry]

Are there any examples or pictures of the 774 series on the net?  I looked but, unless I don't recognize what I'm seeing, I didn't find any.

I still don't quite know how these fittings are supposed to be assembled to make a different style connector.  The "double banana" arrangement is obvious enough, but don't understand how the other fittings are supposed to be used.

Thanks again,
Barry - N4BUQ
