I've used an 8 ohm wire wound power resistor and never had problems.  I
did this so my buddy who plays lead guitar could get the "amp" sound

speaker in a closet with two matresses.

I had heard of this potential damage, but I think it's a myth
created by manufacturers of commercial dummy loads.  (c;
