    bought an NOS 6V6GT tube which i recieved today. it's missing a pin which i thought obviously means it's faulty. but having searched on the net i'm finding that sometimes pin1 is ommited. is this true? am i right in saying the round bump at 12o'clock is the key, so the missing pin is pin6 yes? which just means the tube is no good? just want to check before i return it.

    Pins 1 and 6 are not connected electronically to anything inside the tube, and they were frequently omitted from the tube bases. Yours does look like it was broken off, not just omitted, though it should theoretically not make an itoa of difference.

    99% sure you're good to go to use the tube. However, if that tube was sold to you as NOS, I'd be a bit confused, as a broken off pin implies it was installed in something, which means it's not technically NOS, though the exact details of your purchase may have a loophole.
