Yes, I've had a similar thing with mine. The amp is racked, but it had been stored for a week in our rehearsal room in the cold and damp. After a while it cleared up, but after the rehearsal I took it home and kept it at room temperature, tried it again the following week and it was fine.
I didn't think it was anything too serious as the amp had just been serviced by Ashdown.
