I've been browsing YouTube for Alice Cooper videos (I'm a big fan of him) and found a few clips of him performing live in Detroit 1971 on a show called "Tubeworks", interesting thing about these clips is I saw some TK-42s in the background and the pictures look a little similar to a TK-41 except it halos more easily due to the vidicon tubes being colour filtered and the orthicon tube being fully exposed like a B&W IO camera, I found the footage very interesting to watch as I always wondered what sort of pictures a TK-42 gave opposed to a TK-41. I would have to agree that the pictures on a TK-41 are more superior to that of a TK-42 but looking from a video artistic point of view I find the pictures on the TK-42s very interesting.
Anyways here's the link to the video clips:
