I'm new here, and I know very little about disc cutting. I'm an electronic engineer, not a recording engineer, but this looks liek the place to ask some specific questions:
Recently I have become interested in RIAA equalization and the various arguments that exist, such as the "Neumann 4th pole", innacuracy (or not) in cutting amplifiers, and the exchange that took place between CD4cutter and Cohearent a few years ago:

(I still can't decide who was right!)
I don't know much about lathes, but I do know about circuits. I would therefore love to see some schematics of the inverse RIAA filters using in cutting amplifiers, so I can make up my own mind about these arguments. Is anyone willing to share with me? If you don't want to send whole schematics that's OK, I would be happy with cuttings of just the important filters.
As an experienced analog engineer, maybe I can reciprocate by helping out with any electronic questions others may have on the forum
