Two or three screws on the perimeter of the turntable. Screw them "UP" until the turntable bottoms out. Masking tape the Tonearm to the pedestal in addition to the pedestal clamp. If the ride isn't too long or bumpy, you should be good to go. If long or bumpy, I'd pull the tubes out of the amp, marking EACH ONE per the DIAGRAM, wrapping them in T.P., and put them in a separate box.
Once you get to the new house, install the tubes per the diagram. If you didn't take them out, reseat them, undo the turntable screws, and remove the pedestal clamp tape. Plug it in and enjoy. Advise them is will probably need a recap of the amp and preamp in the next year or so to maintain SAFETY, and longevity of the unit.
