GM Labs #2 Visitron Tube  
Written by AnubisTTP on 2007-06-18  


'Visitron' is yet another brand name concocted by tube companies to take a pedestrian argon filled phototube and make it sound new and exciting to the consumer. Despite the cloying name, the tube itself is actually quite attractive, with a large curved envelope and a four-pin phenolic base. Interestingly, these tubes appear to be individually serial numbered; the example shown here is numbered 304,279, which would represent a shockingly large production run if it is to be believed.
