ZZ1030 / STV500/01 quad voltage stabiliser
The structure of this device is four separate voltage regulators held within an evacuated glass envelope. Each element consists of a glass tube connected directly to the base. The relevant base pins for each run directly into the glass tube. The tubes are sealed at the top and supported in mica. Pin 5 is listed as no connection but in fact connects to the getter ring.
