Lower gain in left channel.


I just noticed last night that the volume from my left speaker is lower than my right speaker. It is enough that images are pulled towards the right speaker, but it is not glaring. Could this be a sympton of a power tube going bad? I'm running An Air Tight Preamp (with 6 month old new tubes) and a c-j Premiere 11A. I'm not sure the age of any of the tubes of the c-j, I bought it used and have had it for about 1 1/2 years. Would a tube or tubes going bad manifest in this way. There are no strange noises or anything coming from the left channel, just the slightly lowered gain. Thanks for your help.

I would suggest narrowing the problem to a particular piece of hardware. Maybe you've already done so, but I would swap the cables between preamp and power amp, and swap speaker cables or speakers whichever is easiest. I had a similar problem with a pair of electostatics and it turned out to be the crossover in one speaker was bad. Oddly enough it was the speaker that was loudest that was the culprit.
