The 7475 is a neon filled voltage stabiliser tube with good regulation.
Seen from the top 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 2.0 Volts.
See also 7475 for an exhibit without its base.
The wide glass tube envelope is 25 mm in diameter, and excluding the B4 base pins is 60 mm tall.
