Remove the power cord (on newer amps) or coil the cord and insert under the handle.

Remove the back of the cabinet.
Carefully Remove the tubes.
Carefully wrap the tubes in bubble wrap.
Place the wrapped tubes inside the cabinet then fill the cabinet with bubble wrap
Replace the back, and screws. Make sure the back is a little snug but you should not have to push hard to get the back on.

Put wrap on the sides of the cabinet (top and bottom in this photo)
Place a a strip of bubble wrap on the bottom of the box then lace the amp into the box. Note, you must use a sturdy box intended for shipping.
