@billstevenson good luck with surgery! Thanks for your input already.
I noticed that the MW-1 cyclone is allegedly quieter, so that is a big selling point. Is it possible to put a small spacer (say 3–5 mm: vinyl, acrylic, leather, wood) on top of the VPI cork platter to give the record a bit more space? Not sure how much hight variation the vacuum tube can handle.
Or can the platter be removed and replaced with smaller diameter one? Is it screwed on or welded?
@joenies Thanks for your procedure. I want to take the record out of US and dripping wet right away onto vacuum. Otherwise any suspended particles in groove have a chance to settle again onto vinyl. I also use RO water (have whole house RO, so is "free") and by quickly removing dirty RO water with vacuum should remove all particles. Listening test have found the RO/Vac cleaned records to be dead quiet. I actually want to do some trials and look at records with scanning electron microscope to see if there are any differences with respect to RO/Vac vs.+DI/Dist.-rinse. I doubt it.
@bdp24 Re Pro-ject, see first post. Two of those died on me in ~1000 records, so will not buy a third one. But you are right, this is what I am looking for.
Re adding disposable paper on the cork platter, not practical doing 50–100 records in a day.
@howardlee 40 years is pretty good, IMHO. Record doctor with manual spinning is not a good option for cleaning lots of records (50–100/day). Appreciate the pointer, though!
