Well, I can only speak from personal experience and not from the theory
side of the equation.  However, I have ALWAYS carried in my gig bag a few
50W to 100W, 8 to 10 ohm resistors packs wired to the popular amplifier
output connectors like dual bananas and 1/4 phone.  I have used them
repeatedly in situations where amplifiers would have otherwise been left
unloaded (both tube and solid state).  I have never smoked an output stage
doing so.
