The Orthicon 1840

This short-lived and warm golden looking tube was developed at RCA by Albert Rose and Harvey Adams in 1939. Except for its size and shape, it didn’t have many technical advantages compared to the bulky Super-Emitron and Super-Iconoscope tubes which were performing well and continued to be widely used until the advent of the Image-Orthicon.

This tube is 14“ (35cms) long, with an 8-pin base and four front connections.
