The GE PE250 Early Color Television Camera

[J Ballard]

Hi all-

In an earlier post, I mentioned that the Museum of Broadcast Technology (Woonsocket, RI) would be receiving a GE PE-240 color film camera shortly. Sure enough, last week a shipment arrived with the GE in good cosmetic condition, but when the top access door was opened, it was completely absent yokes, tubes, and optics! Plus the dreaded encoder .Groan.

Still, some observations can be made about this camera. First, the build quality is excellent. As with RCA, GE Electronics Park was a defense contarctor, so the wiring and layout were of top quality. The optical bedplate had to be 5/8"-3/4" thick aluminum.

There were test points on one card for masking (color matrix), suggesting a variable matrix-something not available on the TK-27. Also, there was reference to the GE "AutoTrast", unless this was a module also used in the live camera. This was an auto knee circuit that became common on Japanese and European ENG cameras.

But, there was a muffin fan on the ear of the upper housing, and from photos seen of the GE 4V design, the deflection assemblies and optics were not enclosed, as in the RCA designs. If so, I bet dust was a serious problem.

If anyone has the missiing pieces to a PE-240, please contact off list-TK41C@aol.com.
