SilverSport Posted July 19, 2007 Share Posted July 19, 2007 I have a pair of Tubes that I got and I am not sure what they are exactly...any help would be greatly appreciated... green tip xxN-CEP 7308 (I can't make out the letters anymore where I have the "x"s) in white Made In USA in white AMPEREX in white gold pins there is also x5-13 or x5-43 where I can't make out the number where the "x" is (the "x" is my substitution) Thanks, Bill Quote Link to comment Share on other sites More sharing options...
SilverSport Posted July 19, 2007 Author Share Posted July 19, 2007 I found Brent Jesse's site that seems to point to my Amperex as being Military grade USN-CEP 7308 (6DJ8) any more information (or a point in the right direction) would be nice...
