Maybe try Google? As I said, I downloaded them I didn't rip them myself. There was this person with the username "PBTHAL" that always had to best lossless vinyl rips, if you do a search that includes that name, you might find alternate download sources for them. I think they ran their own site where they posted all of their rips outside of what, but don't know if it's still there. They were also very thorough while explaining the process, equipment, cables, etc. for each and every rip. This person was really a perfectionist, and boy did it show. There were albums that they ripped and then refused to upload because they didn't feel their rip was perfect enough.
Absolute fucking legend.
I even have FLACs of reel-to-reel versions of all Zeppelin albums, as well as, Bowie, Dylan, et. al. and they sound fantastic. Don't ask me how it's done. And given the pedigree of that website, these people took the ripping process incredibly seriously.
