Amplifiers and cabinets
How to handle weight, protruding controls, valves, speakers and the structure of amplifiers and cabinets.
On heads and combos, identify protruding parts first: knobs, switches, jacks, handles, feet and corner hardware.
Create clearance and protection around these areas without using knobs as bearing surfaces. For heavy equipment, the lower protective layer should support the load without collapsing quickly.
Do not treat the amplifier handle as a structural part of the shipping package; the weight should be supported by the packaging system as a whole.
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.
