Hg vapour rectifier, 1 phase VU72 from National Valve Museum:
The VU72 was the pre-CV RAF code for the commercial mercury vapour rectifier type GU50. The latter exhibit has a clearer glass envelope and so the internal structure is easier to see. The maximum reservoir capacitor is 4 µF. The filament is a twin horseshoe of corrugated tape. The anode is a short dustbin lid connected to, and supported by the top cap.
