Sensibly equivalent to:
C1C
    
Extras ▼

 

The CV1400 is a current stabiliser or barretter based on the commercial C1C. For voltages between 100 and 200 Volts the current varies by only 30 mA. If a pure voltage source is connected across a barretter the filament will be destroyed, it has to be in a current limited circuit.
The iron wire is coiled to allow maximum length in a small space. The envelope will have a hydrogen filling.
The wide glass tube envelope is 39 mm in diameter and, excluding the B4 base pins, is 113 mm tall.
