Hi, Dennis,

Is it correct to assume that the eq used by a given company at a given time, on ethat made its own phonographs, 

When a record company also made phonographs, as so many of them did through the late 340s anyhow, is it safe to assume that the non-adjustable playback eq hard-wired into the playback amplifier matched what was used to make that company's records at the time the amplifier schematic was drawn up?  And, if so, could these schematics be a source of accurate playback curves for that company at that time?

In fact, what emerged as the RIAA playback curve was one of those originally published by Western Electric and used occasionally by Victor, Columbia and HMV in the late twenties. However, it was used far less than those customarily associated with 78rpm playback
