Hi! I am interested in the valves VR18, VR21, VR22, VR27 and VU33 which are used in the GB aircraft receiver R1082 and the VR99, VR100, VR101,VR102 , VI103 and VR99A used in the R1155. I have both receivers in my collection and also some spare valves. When looking at these valves in RMorg I find some confusion with equivalency among valves numbered in the different numbering systems. I have compiled a list which I would like our GB experts to confirm, complete and critizise!! After that I hope the valve admins will complete the listings and I have pictures, measures and pin assignments to add.
In 1941 the GB military services started to use the CV numbering system, common to the Army, Navy and Air Force. Before that the Army used the first letter A, the Navy used N and the Air Force V, with the second letter R for receiver, T for transmitter, I for indicator valves and so on. In RMorg many of these valves are filed under the 10E numbering system which was the Air Ministry storage ref. no. and in my opinion not really a valve designation (although it was printed on some valves) and no pointers are showing the equivalents in the A, N, V and CV systems.
The following list is compiled from data in the CV Register of Electronic Valves Dec 1944 and from the Virtual Valve Museum data (Jeremy M. Harmer):
VR18=CV1018=10E/7607
VR21=CV1021=10E/7738
VR22=CV1022=10/E7958
VR27=CV1027=10E/8239
VU33=CV1033=10E/9829
VR99=CV1099=10E277
VR100=CV1100=NR64=10E/278
VR101=CV1101=10E/280=MHLD6
VR102=CV1102=10E/279=BL63?
VI103=CV1103=NR69=10E/305=Y63
VR99A=CV1581=10E/757
I suppose it is not possible to get a complete cross reference list but at least we can make it for these valves!
