Questions about tubes and gear that glows. FAQ

Re: You're right, E is May....F is June...<nt>

Thank you for all your help.

I feel pretty good about my purchase. (considering they cost less than Sovteks)

Out of the batch that I bought, there were some that were made in the U.S. (it has the * etched code (Amperex, NY) right?) But, the tube still said Made in Holland???

One other difference that I noticed between the Dutch (Heerlen plant) and U.S. ones was that the Dutch ones do not have the perfect glass envelope. They have a very slight dent near the middle. But not so much as the pinched waist ones that I've seen pictures of.
Could these be considered pinched waist?
