All the tubes were contained in a padded box within the main box (not in the sockets). Inside the 'tubes' box, each individual tube was within it's own custom shaped box... Extremely well packed, and yet still damagedGood instincts - that cant possibly be how a good tube is supposed to behave. Was it shipped in place - in socket? Package may have taken a good, solid landing somewhere long the way, which could have moved some structure inside it slightly.
