I'm not gonna refer to myself as a newbie, that's a Gearslutz term & well... enough said on that. I've also had some basic disc cutting experience/knowledge in the past & trying to get back into it, I need to relearn some of the basic workflow & technical points, I have a couple of questions I could do with going over and would appreciate any help, even if it's pointing me in the direction of an older post or a good reference. It's not easy finding good info and you guys know best.
I'm also gonna ask all these questions with a VMS-80 in mind as it's the only lathe I know (I use the term 'know' loosely).
So here are my few dumb-ass questions to get me re-started:
1. Why do I need to send the preview signal to the cutter head? I get that a feedback loop is fed back into the amp to lower distortion but if it's for the purpose of monitoring the audio before it's cut or for the pitch computer to look at the advanced signal then why does it go to the cutter-head first & not the amp, which what I remember is fed the mod? I can remember the delays times for different playback speeds etc.. just need to remember the point- fully.
2. The RIAA filter, where in the signal chain does it empathise & de-empathise??
3. I can't remember why I have to align the crosshair with the stylus in the side microscope, it's so the swathe discharges into the tube correct maybe, can anyone shred some light on this?
4. How does the lathe know the size of the disc i'm cutting? Is it purely from changing the size on the turntable itself or is there an alignment process.
5. When I cut markers and fast grooves, what exactly is it cutting, silence with a large land so that it's clearly marked on the disc

Thanks for any help, I know i've asked a fair few questions here.
