F.S. 1960 Vintage TV Camera Tubes: I am offering an actual RCA Vidicon camera imaging tube which was used and was functional when removed from service in 1965. Also, a very nice booklet of the theory and functional behavior of the Image Orthicon Tube. The Orthicon tube was used exclusively in studio and most remote TV broadcast Cameras for many years, until color TV replaced it. I have owned these for many years, since I worked in that media for several years in the 60’s.
I am selling these items for $100, which includes shipping and insurance to the contiguous
48 states.
You may contact me via this ad for any questions. Both items are in excellent condition.; Listing #1757453 - Submitted on 01/31/26 by Callsign K9AU - IP: 210-253-182-166.mobile.uscc.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
