Well, I think I've found the part. It's a Laird CM3312R111R-10. It's a an SMD common mode choke chip. It's a very unique package. I looked at over 2000 pictures of other components and this is the ONLY part with the footprint and terminal layout.

HOWEVER...according to Digi-Key the part is obsolete and they have none in stock and can't get any more. I haven't checked other distributors.

I took the cover off my mix to verify the part and found something I didn't expect. There was a new and different part in place of L7 and L8. They were bigger and appear more robust and there was a bit of trace rework. This can mean one of 2 things.

1: The part that was in there originally was indeed the Laird part and it is indeed obsolete and AVID had to substitute the parts in there just to get it to work again.

2: what was said in #1 above AND these parts and the rework was done to address the issue many have been having with the Mix and this was part of an ECO.

If 2 is the case, anyone sending the unit back for repair should have a more reliable Mix in the future.

I'm keeping my router earthed and my Mix PSU IEC plug lashed to the PSU anyway.

Hope this helps.
