Here's the basic concept that's worked for me 4 times to date, including a 21 rectangular CRT. It's basically the same method that manufactures used, plus some extra padding added around the bulb portion of the tube. You don't necessarily need to use soft foam, but you do want some significant thickness of shock absorbing material surrounding the face and sides of the CRT bulb(the heavy end). The key is to only pack around the bulb portion of the CRT, leaving the neck to float in the free space inside the cardboard gridwork. Ideally you want some compression between the front of the CRT and the rear cardboard grid that cradles the back funnel of the CRT. Absolutely DO NOT substitute foam peanuts for the packing material, as they will shift.
