Sylvania 6476A Dekatron Tube  
Written by AnubisTTP on 2006-10-11  


The Sylvania 6476A is an early USA-made neon filled selector. This tube is double guide, with a run-of-the mill 4kHz counting speed and a 12 pin duodecal base. The example shown here has seen heavy use, resulting in a very uneven glow discharge across the cathodes. Sylvania was a prolific manufacturer of dekatrons and the 6476 was one of their most common models.
