Telefunken red tip


Anyone have any insight as to why Telefunken marked in red the very tip of some of their ecc82's?I'm guessing it went through perhaps special screening for medical or specialized equipment?

Brent is extremely knowledgeable and  a nice guy.   I have a few NOS tubes that were from him that I got in a trade.   High quality and geuine,  he is one of the best sources for NOS tubes out there.
