@holmz , I have a program called Pure Vinyl. I can digitize and catalog vinyl. I already have an ADC. My phono stage has been digitized for 20 some odd years now as my preamp is digital. Pure Vinyl also has digital RIAA correction but you have to have a phono stage with a flat or uncorrected out put. I have one on the way and plan to try it. There are people who think it is superior to analog correction. Yes, you can record multiple versions of any situation and compare but it does take a lot of time and work. I do compare digital to analog versions of various recordings by synchronizing the record to the digital then just switch back and forth by remote. This is pretty easy to do and a lot of fun. It also takes little time. You do have to purchase multiple versions of the same recording but I suspect most of us do that anyway.
Great that you got a CB. All the adjustment grub screws have nylon inserts so they do not leave marks. You only need a light touch when you tighten them. Don't over do it! Be very careful with the lead out wires. They are tougher than you think but still, having to rewire the entire arm would suck. The axis of the horizontal bearing has to be 222 mm from the spindle. A 1" hole will work perfectly. It really should be done on a drill press. If you have any issues feel free to message me.
