The 7475 is a voltage stabiliser tube. This exhibit has lost its base and looks to be in a poor state. See 7475 for the complete valve.
Seen from the end the two concentric circular electrodes held in place by a mica disc is clearly visible.
The striking voltage is 140 volts and it will hold the 100 Volt stabilised voltage for tube currents of 1.0 to 8.0 mA to within two Volts.
The wide glass tube envelope is 25 mm in diameter and, is 50 mm tall.
