Conventional Fixtures Source for old two-pin connectors?

[Objectivist]

Actually I'd be suprised if Opera Shop or InnoGroup or whatever their name is these days has one laying around. DCPA might have one attached to an old light somewhere, or better yet you might give the TD at the Macky out in Boulder a call.

Thanks! I'm still hoping that gafftapegreenia will be able to help me out, but if not, I'll give Macky a call. (I am indeed in Denver.)
