Is it possible to take my combo and take the speaker wires from the amp, and add a jack so its a cabinet? On the manual for my amp its says 8 ohms are used by the speakers together
SS amps are fine if you get a decent one, no they don't sound "as good" to some people but they also don't break down on you and need to be continually refitted with tubes. Just keep that in mind. If you are out on the road, SS is the simpler, more easy way to go.
You can't die while it's unplugged really...no monster caps(still, you can't sue me if you do.)

Just touching the speaker leads is pretty harmless in all events.
