Index of Valve Equivalents

Please note: Valves from the series ACR, AR, ARD, ARH, ARP, ARS, ART, AT,
AU and AW appear under British Army. The series NC, NG, NR, NS, NT and NU
appear under British Navy. The series VC, VG, VI, VR, VS, VT, VU and VW all are
to be found under British Air Force.
It is normal practice that valves from different manufacturers are `sensibly equivalent' rather than identical.
9,000 references, matched to our database of exhibits and non-exhibit data.
Last updated 28 December 2008.
Each of these references has been found from vintage literature.
Some errors in the originals have been corrected.
We may have introduced others.
Please contact your webmaster if you discover an error. We have tried to use primary sources if possible, i.e. manufacturers listings, in the absence of primary listings we have used the AVO Valve Data Manuals 17th & 20th editions 1965 & 1974 as well as numerous other publications.
