Amplifiers: handle valves, speakers and internal parts deliberately

For valve amplifiers, check for obviously loose parts. If the manufacturer, a technician or the transport procedure recommends removing certain valves, identify their positions and orientation and pack them separately with suitable protection.

Do not improvise disassembly on equipment you do not understand. With combos and cabinets, also consider the mass of the speaker and how an impact can load panels and mounting points.

Before closing the parcel, carefully listen for loose components and address them without opening hazardous electrical areas.
