This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.
it would be a good idea to have a post where to be able to find schemes to be able to make we ourself previous riaa for cut, for a mono presto, or a haeco sc2 with feedback ...
