Fluctuating volume in one channel


I just noticed that the volume in the left channel was substantially lower than the right. I started switching the balance from left to right to verify this. I did this for about five minutes and I noticed the volume in the left speaker varying from slight volume to the correct volume (equal to the right speaker). Now everything is fine. This was while playing a familiar cd.

I also tried switching between mono and stereo while this was happening. I didn't have enough time to play with this to be 100% certain, but I'm ~90% certain that while in mono the levels were equal. It is hard to say, though, because the volume level in the left speaker was changing while I was playing with the balance and mono/stereo button.

Has anyone experienced this before? I have a tube CDP as well as a tube preamp. The amp is SS. Can tubes behave like this if they're going bad, or is the problem likely somewhere else?

Any help would be appreciated. Thanks.

When it happenned to me, I had a bad solder joint in the IC's. 2 minutes with the iron fixed it. Funny what you get when you but $2200 retail IC's here on the 'Gon for $75.
