I am pleased with this build. If you have a 3d printer, you may want to give this build a try, or if you see one of these resonbly priced. This was about $150 to $200 build. Got the 6 liter ultrasonic cleaner on Black Friday sale. Could get a cheaper one as long as it is 6 Liters. Then bough 1 Rpm 12 volt ac motor, and Jamco electronics 12 volt ac wall wort and mating dc power receptacle, 6mm threaded rod, and 6mm to 7mm coupler from Amazon. I hear 40 kHz ultrasonic cleaners are best, probably could go cheaper with an unheated or non-digital unit as not sure if heating helps.
Besides moving some of the pops and cracks, also improved bass response and mods and high detail noticeably for many of my used records. Word of caution though, it is loud and annoying when operating. I clean my records for 15 minutes on 25 deg c with one capful of record cleaner concentrate added to distilled water. The. Wipe and dry with clean microfiber, then give a final anti static brush wipe and records sound better. Not like new, but very noticble improvement over using just a brush, or brush and microfiber and cleaner.
Below are some mother-in-law, unjacketed basement records. Got a whole box of dirty records with no sleeves or jackets. Many sound pretty good. Makes even the lightly used well kept records from record store sound better.
