Nuforce STA200 issue. Rumble every couple minutes

I just picked up a used NuForce STA200. 

I have it connected to a low gain tube amp, ~6db

If I let it sit there with no music (same with music) it will cause a major 'rumble' and the speaker driver is pulsating like crazy for a couple seconds. 

This happens every couple minutes. 

Any ideas?

I’ve had 3 over the years, though match could be difficult, never any problems...always worked well with passive pre, and for me a great match with Schiit Freya S preamp...and low efficiency speakers
