They are totally remastered from the original mixes, not from the raw original tapes. They were not remixed, which is why the early amateurish stereo mixes done by technicians without input from the band or George Martin are pretty crummy compared to the mono mixes. The early mono albums have a significant "wow, that sounds great!" factor which is not found on the stereo albums.
