|Written by AnubisTTP on 2008-02-16
The 0Z4 is an argon filled full wave rectifier tube. Most 0Z4s have an opaque metal envelope, the example pictured here is the somewhat rarer glass envelope '0Z4G' variant. As can be seen in the photo, the glass version of this tube allows the argon glow discharge to be seen during operation. This tube is designed to fit in a standard octal socket, though only five of the eight pins have been populated.
