Even the most reputable tube vendors are able to test crooked tubes.

Yipe!, well, to give them the benefit of the doubt - that bend could have happened *after* it was tested, during handling / storage / shipping. Generally the experienced employee's wouldn't force something onto a tube like that, but there might be warehouse or shipping / order fulfillment people without "hands-on" knowledge about tubes that bent those pins.

Speaking of "there", where did you buy this damaged tube? And, what did they say when you sent them the photo to start the RMA?

bent pin per se is no big deal -- although it suggests that the tube is a pull rather than a new tube.
It would be hard to do that removing a tube from a tube tester socket IMO and IME.

You (the OP) should probably invest in a pin straightener. Heck, many tube testers have pin straightener sockets built into 'em! :)
Trying to straighten a pin "manually" (e.g., with pliers or hemostats) runs the risk of cracking the envelope and releasing the vacuum... umm, I mean, not releasing the vacuum... urrm, ehmmmm... you know what I mean! ;)

Releasing the vacuum-funny, that. What, exactly, escaped? How about losing the vacuum?

RCA stopped making tubes in the '70s and warehoused 100 billion of them to be replacements for the life of existing equipment. Why would anyone manufacture tubes now? They aren't nearly as vulnerable to EMP but why else use them?
