Amplifier Goes into Protect Mode Right Channel


Wanted to hear your tech thoughts on this problem. After spinning vinyl for 1-3 hours, the right channel on my solid state amplifier goes into protect mode. This repeats itself multiple times each session. I have a tube preamp and tube phono stage. Only one source - turntable. I've swapped tubes in the linestage preamp which made no difference; swapped IC cables which made no difference. The linestage tube preamp is new (one month old) but I'm beginning to think it may be a leaking cap causing the trouble. Also looking at the speaker cables as a possibility. Would that matter? Any thoughts? At the point where I'm ready to RMA the preamp for bench test. Thanks in advance.
