Valvo 90AG Photocell Tube  
Written by AnubisTTP on 2007-09-05  


The Valvo 90AG is a British made argon filled phototube in a standard seven pin envelope. The 90AG is designed to be most responsive to light in the blue range of the electromagnetic spectrum. This tube has particularly good print quality on its part number and logo; it is not quite up to the standard set by Western Electric tubes, but is far better than the typical "dissolves when looked at" print used on most tubes.
