Margot---Good question, and the answer is, because the vacuum tube is self-leveling, you don't have to worry about any increased pressure. I've been adding the extra mat for dirty records on my HW-17F for years.
using extra mat VPI 16.5?
For those who advocate using an extra cork mat for the "clean" side when cleaning records with the VPI 16.5, do you just put it on top of the existing "dirty" mat? I am a bit concerned that raising the record in this way might put too much pressure on the vacuum tube? Thoughts?
Thanks! Margot
