Bad caps???

I have a BAT VK-3ix preamp that I think is having some kind of issue. I got this unit used several years ago and recently I’ve noticed that every now and then the right channel gets distorted. Almost like a radio station just out of tune on an old analog rig. The sound also drops in and out of volume slightly. This only happens for maybe five seconds and generally within the first 10 min of operation.  I’ve replaced and swapped tubes around but the sound still persists.

The unit is probably 10 years old by now. Is this what bad caps or going bad caps sound like?

I had exactly the same problem a few years ago with a McIntosh preamp.  I sent the unit to Mac and they sent it back with a clean bill of health.  I put it back into the system and had the same problem.  Out of frustration I swapped out the patch cord, and the porblem disappeared.  With the 'intemitent' aspect of the problem I would have not imagined that the cable was the culprit. Now its the first thing I check when an issue comes up.
