Why not copy the greats- vinyl LP question

Where's the Zeppelin?
I guess take your chances with Ebay.

When the world went digital, record labels had their analogue masters transferred to digital tape. These became the new masters. As digital technology progressed, higher bit and sample rates were utilized.

Jimmy Page did go back to the analogue source tapes, which allowed him to remix. But, these tapes were transferred to digital. There's a very good reason for this besides being easier to work in the digital domain. Nobody would want these old magnetic tapes threaded through various ATR's and shuttled back and forth during a mixing session.
 

so there was very often a dub of the master mixdown made for LP cutting. So aside from extra limiting/compressing there was also an extra tape generation or more. Compounding the problem, many engineers that did work liked to label the tapes they worked on as "master," so it could be confusing to find and use best available tapes for reissues over the years.

True, And there was more than one of these "masters" for cutting, each record plant received a reel, eg, US, UK, Germany, maybe Japan. This was during the great days of analogue production.

Do you know how many LPs of an artist Analogue Productions typically issues? 
How many units, as they say in the biz.

Thanks for that in-depth answer. And for including the info about "Kind of Blue"...fascinating.
Used AP releases on Ebay can fetch high prices. And a modern reissue from a major label costs the same as your $35 gem.

I've collected early and 1st issues so I'm aware of the  process. I have a pressing that has -1/-1 in the dead wax; 1st stamper, 1st run. But I learned it could mean I have pressing #1 or pressing #2000.
