If the tube gear is going to be shipped via FedEx or UPS I would remove the tubes and pack them separately.
If you are bringing the tube gear in your car and they are buckled up or properly secured I would keep the tubes in. I did that with my Jolida 502P amp once when I was bringing it over to a friends house for a listening session.
