How do you measure output impedance?


I'd like to measure the output impedance of my pre-amp. Is this something I can do with a multi-meter? If yes, how?

That's exactly right. And I had my preamp modified recently with additional resistance on one set of outputs (to lower gain) and would like to know how, if at all, this has affected the output impedance for that set of outputs.

Zoya, your question strikes me as odd. Just because the process is intimidating, why do you suspect my interest in the result?

I've been curious for some time about this issue of mismatch between pre and power amp. I'd like to have real measurements to compare with what I hear to try to get a better handle on things.
Actually, Herman, that all sounds pretty intimidating to me. I'd need a lot of hand-holding, plus a pot. Thanks for posting it, though.
