The main part you are likely to need when repairing is the Hash ASIC BM1384, (U4 - U47). These would only be available from Bitmain, however I suspect they are not selling them, so you will need to remove devices from a failed board to repair others.

Rich I think that P/N is : SN74LVC1G07 Single Buffer/Driver With Open-Drain Output

Yes sorry my mistake, U6, U9, U12 ..... U39, U42, U45 are as you say SN74LVC1G07 The rest of the chips in the Range U4 - U47 are the BM1384
