Ask JJ. They will likely tell you if one is counterfeit and would be happy to have brought to their attention.

These are not expensive tubes. $10 - $12 usd each.

If I were counterfeiting tubes I would choose a much more auspicious and profitable target.

Nobody counterfeits $1 bills.

Look at the pic of this exact tube on the Sweetwater website. Same fuzzy date code.
