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.

What you want is to use heavy dense foam. Then an inner and outer box. It is not too difficult to find two boxes which can ust slide into the other.
The foam should be at least 3" thick all around the amp.
The bigger the box, the less likely the box will be tossed around. (in my experience)
Packing tape all around in all directions can strengthen a box dramatically.
Several layers of tapecrossing the centerlines in all three directions.
