The GZ34 is an example of a typical high current rectifier for small equipment use. It is indirectly heated but the cathode is tied to one side of the heater.
The transformer HT winding would be centre tapped. The centre going to ground. As each anode goes positive in turn the current flows, this way rectification takes place on every half cycle, and gives the name full wave.
The wide glass tube envelope is 32 mm in diameter and, excluding the IO base pins, is 72 mm tall.
