Jays audio cd transport

Hi, just received my jays audio cd2 mk3 transport. First impressions are amazing. Built like a battle ship.  Plays wonderfully even tho it's not burnt in yet. My only concern is that there is a definite and noticeable hum from the chassis . It does not come from the amp,or headphones. Just wondering if anyone  has experienced the same
Check the bolt on the internal power transformer and make sure it is tight.
Thank you for that. Will look at that, but a bit nervous in opening it up as it may void the warranty
Yeah, maybe best not to open it. There’s another thread about this hum. No solution specified but a suggestion that using a power conditioner or regenerator might cause an issue. Try straight into wall.
