OK, now I am confused...the tubes say made in the USA, has a *5B etched under the VR5, which I am told means made in the USA, but also has the large white triangle (delta) which denotes made in Holland. Please note that the triangle is quite large and independent of any lettering. Am I confusing this triangle with a triangle used in place of the * to denote origin of manufacture??
7308 tube code question
I just received 10 NOS Amperex 7308 from my father. Each tube has the following markings:
All lettering in white
USN-CEP
A white triangle like symbol
VR5 *5B etched in the glass
The only nomenclature that I am familiar with is the USN = US Navy. What does the rest mean? What do people think of these tubes in a phono section of a pre-amp designed to take 6DJ8's
