I know all the techies out there are gonna cringe, but I have an extension speaker jack on my amp, and I plug in my headphones there and unplug the main speaker. I've never done so for an extended period, since everything I read about needing a speaker connected to the amp at all times has got me pretty freaked out about blowing the amp.

That's all I got fer ya.
... and that's all I have to say about that.

CRINGE!!! :eek:

If that's a tube amp, iamthe_eggman, you've been a bad, bad, boy! :mad:

For a transistor amp, driving a headphone instead of a speaker is no problem. :)

A tube amp [u]must[/u] have a load that is matched to the amp output. That's why they have output tranformers with several impedance settings. I've never tried it, but I think it should be possible to add a headphone output, provided you also connect a suitable "dummy load" to absorb most of the output power. Unless the dummy load can simulate the electrical characteristics of the speakers, there will be some noticeable differences in the sound you get in the headphone.

I'll try not to get too technical here...

Basically, the power sent from the tubes to the output transformer has to go somewhere. If it isn't being disipated by the load, it gets converted into heat in the transformer, causing it to burn out. The damaged tranny then causes your tubes to fail. It can add up to some serious expenditures on repairs.

OK, no damage so far (as far as I can tell). I'll be good from now on....
