Maybe someone here can give me some information.  The military, at one time, used a VT number to identify tubes.  That was changed to a JAN number.

My question is, did they use the OEM number and simply add the letters "JAN" to the tube number, or are there tubes that have JAN prefixes like the VT number system that have a cross over number to an OEM number.
