I have both a generic 40 kHz tank and 135(?) kHz sweeping US tank from Vibratto. I use both, and noticed an improvement when I added the 135. I spin the records in the 40 first after applying disc doctor cleaner, and then in the 135 that also serves as a rinse tank. I use the basic first generation cleanervinyl rotisserie and filter the second tank. Air dry with a small fan. Definitely worth the price.
Record Cleaning Machines
Has anyone out there done an A/B comparison of the cleaning results or efficacy using the Degritter ultra sonic record cleaning machine which operates at 120 kHz/300 watts and an ultrasonic cleaner that operates at 40 kHz/300 or 380 watts (e.g. Audio Desk; CleanerVinyl; the Kirmuss machine; etc.)? I have a system I put together using CleanerVinyl equipment, a standard 40 kHz ultrasonic tank and a Knosti Disco-Antistat for final rinse. I clean 3 records at a time and get great results. Surface noise on well cared for records (only kind I have) is virtually totally eliminated, sound comes from a totally black background and audio performance is noticeably improved in every way. Even though the Degritter only cleans 1 record at a time, it seems significantly easier to use, more compact and relatively quick, compared to the system I have now. I'm wondering if the Degritter's 120 kHz is all that much more effective, if at all, in rendering better audio performance than the standard 40 kHz frequency. I don't mind, at all, spending a little extra time cleaning my records if the audio results using the Degritter are not going to be any different. I'm not inclined to spend three grand for a little more ease & convenience and to save a few minutes. However, if I could be assured the Degritter would render better audio performance results, even relatively small improvements, that would be a whole other story.
