I assume this is happening both with phono and another source? This would eliminate something in the phono stage as the issue.
If so, then the easiest trouble shooting is to swap the positions L/R of the valves, one set at a time, powering off in between. Start with the rectifiers, then the tubes in the line stage. If you hear the failure switch channels, you know that tube is bad.
If after doing this the problem doesnt flip channels, and all the cable connections are not bad, you know you have another part failure in the line stage that you will have to seek out a reliable repair for. Probably the best place to start with that might be A23.

That's the exact procedure I would follow.
Keith Aschenbrenner will not service a Shindo piece not imported by himself. He has been very fair to stop imports when they became forbidden by RoHS regulations so he does not accept to work for the ones who do not share the same respect for the law.
