I sent my VAC PA 80 80 amp to VAC and it weighs 68 lbs and most of the weight is at the back because of the three transformers. I have the original packing from 1995 but didn't trust it because of it's age.
I bough a appropriate sized heavy duty box from Home depot and reinforced all four corners and the lifting handles. VAC told me not to use bubble wrap as it will collapse if the box is dropped hard enough, but to use foam sheets and pack the amp tight. I also indicated on the box " HEAVY THIS END" and fragile stickers everywhere. It arrived in one piece. I had VAC supply me with one of their original double boxes for the amp with the correct shipping material for the return trip
