The CV2194 from STV is a high stability, high voltage, low current voltage stabiliser that is directly equivalent to the commercial G400/1K. The priming anode and actual anode are to be connected together in the external circuit.
The STC logo and the commercial designation. The lettering blocks a clear view of the internal structure. There are two vertical plates separated by a space. By one plate is a thin wire - the priming anode.
The thin glass tube envelope is 18 mm in diameter, and excluding the B7G base pins is 45 mm tall.
Reference: Data-sheet. Type G400/1K was first introduced in 1958.
