shipping boxes for heavy electronics


greetings, first post here on audiogon forum. I have a heavy parasound amp that is about 90 lbs, and I do not have original shipping boxes. I took it to fedex and they said they would have boxes for the dimensions of the amp, but not for that weight, as their heaviest box can withstand 60 lbs. I have been looking on the internet that would have a rating of 80+ lbs, but I simply cannot locate one.

Can someone make a suggestion on where to acquire such heavy duty shipping box for electronics? any suggestion would be greatly appreciated. amp dimension is 19"x8"x20".

Thank you.

Rethinking my last post, that packing method will address the box with an 80 pound weight limit but you are better off strapping it to a pallet and using freight instead of ground. Your amp will survive ground unless it gets in the wrong hands and is dropped. Less of a chance dropping with freight.
Uhaul has moving boxes that are sturdy 2 ply corrugated, and if you double box, with sturdy styrofoam sheets (you can get at home depot) you may be able to fabricate a package. I would NOT ship a 90 lb amp this way unless I could find 2 double ply boxes that could nest inside each oter with a minimum of 2" hi density styrofoam around it, and use a lot of sturdy packing tape to seal it all up. I may also be inclined to insert some 1/4" plywood sheets on at least 2 opposing sides to give the corners more stiffness.
A wood crate is the way to go .With the styrofoam insulation at home depot .sold in 4x8 sheets.Most delivery services are not going to try and lift something that heavy . They would use dollys or something to aid in lifting heavy weights .
Elizazbeth is correct. Multiple boxes, plenty of thick foam. I just shipped out my old Carys with the original packing, which included very thick foam, and 3 (yes 3!) strong thick cardboard boxes. However, I have heard that FedEX an UPS can refuse to pay claims if the original packing is not used, or if you don't let them do the packing. So Maplegroves suggestion about using a wood crate or pallet is also a very good suggestion.
