EZ12
EZ12 is a double rectifying valve (tube), first made in July 1938 by Telefunken in Germany. It is typically used for the creation of the HT voltage in receivers and transmitters. Each rectifier can handle up to 500V with a maximum current of 100mA (or 125mA at 400V or less). The filiment is 6.3V/0.85A. Below is the pinout as seen from the bottom of the valve (solder side of the socket).
