I have a couple of solid state amps with preamp out jacks on the back panel (a Peavey 400 and an Evans 200). I can take that signal into a mixer and then use the mixer's headphone connection for quiet practice, if I disconnect the speaker.
My question is will it hurt the amp to run it with no speaker connected? (I know I need to protect the bare wires.) |

It's no problem at all for a solid state amp. But no speaker (or load) on a tube amp would be certain death, and the magic smoke would escape.
And yea, don't let the speaker wires touch.

| You can operate the amp all day long without speakers connected. |

Thanks Mike and Mike!
I also have a Special 130 that will be my "go to" for practice, since it has speaker jacks that I can unplug. |

| Instead of unplugging the speaker just plug a short cable or plug into the power amp input. That's a lot safer than having danglin speaker wires that might short out, killing the output transistors almost instantly |

I hereby nominate Ken Fox for the novel idea common sense answer for the week.
In addition, if you have an effects loop pre out/power in etc etc etc whatever on your TUBE amp, his idea will work there, too. |

| I second the nomination. It was a post from Ken years ago that taught me how to bring old Peavey amps back to life. I've lost track of how many it worked on (clean and re-tension the I/O jacks). |

Tommy I do the same thing with my Nashville 400...run out the back to a mini mixer with headphones and what I did was install a toggle switch in line between the chassis and speaker so when I want headphones I just flip the toggle switch to kill the amp speaker and sounds just like a steel playing through a NV 400
