Even with a perfect box we've had customer in the past with units dropped flat on the bottom from quite a distance without damage to the box. You can tell as the top steel pan tray was bowed from the transformers weight and impact with the ground. I've not had one in some time, but the box was perfect. The problem was not known until the unit was opened.

If there is any major box and case damage, it's always a good idea to call in and have a tech walk you though a couple check before firing up the unit. Back then units could have been saved by simply bending a transformer buss.

On the other side of the coin, a cracked bezel does not mean a bad unit either. Just means we need to ship out a bezel.

If every person that bought a unit and had no damage were somehow required to post, you would see shipping damage is a very small number. And the New Members thread would be a nightmare.
