You NEVER want to ship ANY rig with the tubes installed...!
I did that once with a Heath monobander to the USA: a large tube came loose in 
transit, & it rolled around wrecking itself & the rest of the tubes in the rig 
with it! 
And shipping a piece of gear with a heavy power transformer installed inside is 
just asking for trouble...
I've had great luck literally stuffing the innards of tube radios with crushed 
newspaper prior to mailing: the newsprint keeps everything in place & 
intact...and if you use enough of it, even power transformers won't go on a 
rampage...
