[AMRadio] mailing tubes

[David Knepper]

In years past, large high power amplifier tubes were shipped in a mixture of 
glue and horse hair.

FWIW now days, tubes like the 4CX15000's and 4CX20000's are shipped in a 
foam rubber / plastic "cocoon" which has a cavity that exactly fits the 
tube's outside dimensions and this cocoon exactly fits into the shipping 
box. The cocoon is split horizontally. You open the top of he box, pull out 
the top piece of the cocoon than pull the tube out.

The Big EIMAC TUBEs ONCE HAD THE BIG SPRING SUSPENTION DEVICE IN A LARGE
BOX, BUT STILL I WONDER HOW THOSE WERE SHIPPED AROUND BACK WHEN.

Was it just an awareness thing.
