How to physically move large heavy 100lb amplifiers easily (up and downstairs)


Ideally with only one person, but even with 2 especially if there are stairs involved, how can I move this gear without breaking my back or hurting myself?

Buy a hand truck; it's cheaper than physiotherapy. 

Kent English of Pass Labs once had to move BIG amps up a flight of stairs. He walked them up it (in boxes, obviously), end over end. Not the easiest, but doable - as long as you don't let it slip!  
A keg is a lot bigger and heavier than an amp, and we were able to carry one cross-country with two people just about any distance over just about any terrain. We took an empty 50 lb onion or potato sack and stuck a dowel (broom stick) through each side. You could make one out of an old pillow case, or a large bath towel or two. Mine we called the beer stretcher. You have permission to call yours the amp ambulator.
Hand truck or end over end in their boxes.Either one is not difficult if you're slow and careful.
A hand truck with pneumatic tires. You also NEED one or two CAMLOCK STRAPS to hold the item to it.
