@pryso I’m having a tough time convincing myself to use a vacuum on a vinyl record. It only takes one rogue hard particle that gets lodged into the vacuum pad to completely ruin a record. I know I’m probably overly paranoid about it but that’s my take on it.

Analog Productions reissues are, in my experience better than most previous releases. Chad and the team at AP are doing truly fabulous work—between the mastering choices, pressing quality, and overall consistency, their releases often set the benchmark for how reissues should be done.

A vacuum step can be beneficial depending on the cleaning and drying methods used. The VPI did perform better than either manual cleaning or the Spin-Clean which may be attributed to the vacuum drying step in the VPI.  However, the ultrasonic cleaned record followed with a distilled water rinse and vertical spin drying resulted in the cleanest surface. The important step is spin drying on the spindle assembly in a vertical position. As I stated in my previous post the ultrasonic cleaned surface had between ~95 to 98% contamination removal which corresponds to ~2 to 5% surface contamination remaining. It would be near impossible to remove more contamination with any method unless working in a clean room environment.

@lalitk agreed. I’m also extremely impressed with Craft Recordings. Bought a Bill Evans “Sunday At The Village Vanguard” as well as Ron Carter “Where?” and Art Blakey “Caravan”. All are excellent quality.

thanks for the caution, the idea came from another discussion, do you think 2% glycol by volume is risky?

Do you think adding something to my mix to get a positive/negative charge would be beneficial? If so, add how much of what

yes. Add 2% per volume of propylene glycol to mix. 

In otherwords approximately 1 Oz per gallon of propylene glycol. It’s what is in the Kirmuss solution that gives that charge to attract the bubbles to the vinyl. Add in the tank with distilled water."
