How to Identify which Is the


I recently purchased an all-new stereo system about three months ago. Late Friday night I heard a loud "pop" sound coming out of the left channel. Then, the left channel went totally dead quiet.
I was wondering if someone could help me with a step-by-step logical plan for determining which component is the "bad" or "guilty" party with a dysfunctional left channel. I would think that with changing the speaker cables, interconnects, etc., there must be a good way of determining/isolating which specific component has the problem.
I have high-end tube preamplifier and amplifier. The CD player is a possibility too, since it also has a tube. I wouldn't think it is the speaker, but I suppose that's possible, too.

Thank you!

FWIW; I has a similar problem a few months ago and it nearly drove me nuts. It turns out I had a bad interconnect from the source (phono-pre in my case) to the preamp, and a bad tube in the phono-pre. I finally found it by getting a spare IC (only one!) and testing first one channel then the other, one connection at a time, then trying the bad IC on another source. After that, tracking down the tube was easy (nothing left to look for).
