Cetron CE-1C  
Written by Accutron on 2017-05-15  

The CE-1C is Cetron's equivalent of the RCA 918, an early gas-filled phototube with a semicylindrical photocathode surrounding a central anode. The electrical characteristics of the 918 are extremely similar to those of the more common RCA 930 / 1P40 phototube, but the elongated envelope of the 918 accommodates a photocathode which is nearly double the size of the 930 photocathode. The 918 and CE-1C have a S-1 spectral response and a peak sensitivity of 800nm.
