Definitive info on pre RIAA EQ curves.
EQ is all over the place on different pre 50s electronically recorded records! Even on same label, sometimes from same era! No wonder they posted "For best quality on *X* machines use *X* records. Has anyone ever written a book on early EQ of 78s? It would be interesting. I just thought I had a hard time with my vinyl pressing guys in 70-90s. It was the wild west early on!

I doubt ultimately there's such a thing as 'definitive' for older 78s, but this is my go-to:

There's useful information and discussion here, including the statement " 78 EQ is a nightmare":

I use a Graham Slee Revelation phono pre - lots of info here too:

Re: Definitive info on pre RIAA EQ curves.
Audacity had a thing going at one time with EQ Curve plugins. The links to the downloadable pre-fab plugins are broken. So maybe this project has been abandoned. There is some information here in tables, as well.

Re: Definitive info on pre RIAA EQ curves.
Interesting Stereo Lab article on playing 78s. It addresses EQ issues among other things.
