8 Ohm 100W Non-Inductive Dummy Load Resistor
Can I run this with an 8 ohm speaker to make a 16 ohm load on a tube guitar amp?
Unfortunately impedance does not work this way. You will have to use a single 16 ohm speaker or two 8 ohm speakers wire in series.

Are these safe to use with solid state amps as well as tube?

2 dummy loads for stereo bench testing?
Do you need 1 dummy load for each channel when testing a stereo signal or can 1 load be hooked up to both channels at the same time?
You need two to test L & R at the same time. Connecting the two outputs together will cause either a failure or activate the protection circuitry [if your amplifier has one] and shut down.

Can add a plug and go directly into an amp?
If I soldered something likea Neutrik 1/4 plug (http://www.parts-express.com/pe/showdetl.cfm?partnumber=092-316) to the leads, can I safely plug into an amp as a load? Also is there a positive/negative side of this?
Yes this is common practice when testing amplifiers. What is the reason for wanting to do this?

Is the power rating with or without additional heatsinking?
Generally the ratings for resistors are the power ratings without additional heatsinking. With heatsinking you could safely put a bit more power through it, depending on how big the heatsink is and how well it is thermally attached to the resistor.
