My guy Kevin "Dr. Groove" Gray did the OG pressing of A Ghost is Born which is the copy I have. Doesn't seem to have been reissued. The others are done by a bunch of different people:
BG did the 2009 Being There 2xLP (pressed at Pallas).
OG Sky Blue Sky is Stan Ricker half speed mastered and pressed at RTI. 2020 reissue used the same plates it seems.
2020 Summerteeth is CB pressed at RTI in the US.
Not sure about Yankee Hotel but the 2008 was pressed at Pallas I think. Says it was mastered at RTI on discogs too.
No wonder all their records sound awesome...
