RE: Fake Tubes/Bad Seller?

Manufacturers routinely bought stock from other manufacturers and put their own brand on them. I would think that the brand would be much less important than knowing if it is actually a 7316 rather than a garden variety 12AU7 or some other variant.

Is there a way to tell the difference, either visually or with a tester. Did Amperex have a unique date-coding system? That might still be on the tube.

I would think it more likely that the seller simply described the tube as labelled.
