I don't think you will have a problem. My guess is that each amp will consume about 300 to 400 watts each, maximum. That means both amps and a preamp in the same outlet will have as much of a power draw as a desktop computer, monitor and printer.
Look at the owner's manual. Unless it specifically calls for a separate outlet, you will have no problems. The UL listing means it is safe for standard 15-amp branch circuits.
The reason that two hair dryers tripped circuit breakers is because both draw over 2400 watts, exceeding the 1800 watt maximum that a 15-amp circuit breaker protects (maybe there are lights on that circuit as well). There is no way your rig will exceed 1800 watts -- unless those hair dryers are used on the same circuit.
