Yes, there are tube dampers on the 2 6h30s. They are the UltraSonic Hal-o dampers. I will work with ARC to resolve this. It might just need some service.
@Elizabeth I wish it was 3 feet. 3 meters which is about 10 feet away from my listening seat.
It's more of a hum with some hiss and a slight buzzing. I've ordered new tubes. And I'll disconnect all the sources one by one to see if that helps. The spec sheet says 14uV IHF weighted so on paper, it should be nearly dead silent.
