G-RAID 12TB drive enclosure failure

I have two of the 12TB RAID 0 drives in my very large collection of drives. (I also have 5 of the 8 bay shuttles with the biggest being the 144TB) In any case, one of the enclosures for the 12TB two bay RAIDs has failed…it just won’t come on. Changed out power supplies. No go. Is there a way to buy another enclosure? Or is there a way to have it repaired?
