Double image in viewfinder

[Eli Arenson]

I have just bought a modified LTR7 with a videotap and two zeiss superspeeds (mk1 12mm 1.2f/s & mk1 25mm 1.2f/s).

 

Everything on the camera looks and works fine, except;

In the viewfinder i can see a very noticeable double image - especially when shooting a practical light.

I doubt this would be the lenses, since i've checked both, and they both produce the same double imaging (plus i trust zeiss)

I want to blame the videotap which was added by Visual Products. I'm not sure how to deflect the beam-splitter so i can check this. Anyone know this Visual Products videotap and how you can deflect it (http://visualproducts.com/storeProductDetail01.asp?productID=741&Cat=11)?

At any rate, i really want to believe this is a fixable problem, and just requires some adjustment.

i've never ran film through it, so i can't say if the double image is captured on film.

Anyone run into this problem? I'm in contact with the seller, but i am so nervous i'm asking everyone i could think of...

any help would be very appreciated.
