Perhaps you could ask your builder how he arrived at that conclusion, and whether he has a hypothesis to explain it. It does beg the question as to whether the AC signals induced onto the cathodes by each side of the filament are necessarily in phase. It seems like a simple thing, but I've never tested for it.
