CV Register of Electronic Valves
CV Register of Electronic Valves Issue 1, Dec 1944 (Cover)
Since 1941 the Inter-Service title "CV" has been used for names of new valves instead of the previous individual Service type designations (NR, AR, VR etc.). The system has now been extended to include all valves used by the Services and this book is a complete register to the date of issue.
The register is in two parts:
Part "A" contains mainly those valves newly introduced into Service use where a functional description is necessary.
Part "B" contains those valves already in Service use or standardised as more or less well known commercial types, where a functional description is not necessary.
Governing specification: this column indicates the source of the specification to which the valve is accepted by the Services:
AD = Admiralty (UK)
