You are right that red series or any valvo label tube could be from Valvo Hamburg or Heerlen or other Philips sourced tubes.However, color codes meant something is the jist of the posts in this thread. The point here is that VALVO RED and other color codes related to different specs, and THAT IS an indicator of the quality parameters like mtbf etc.
At one point, my friend who retired from Valvo offered to send specs of different color codes. I may be able to get it from him if you are interested.
