No such issues with a Degritter here. 40kHz/60W doesn't sound overly powerful. so I wonder if it is a heat issue?
ultrasound record cleaning machine damaged my records
I recently purchased an ultrasound record cleaning machine. For reasons which I hope you understand I won’t name brands, because I am not wanting to make bad publicity to anyone but to discuss the matter.
Previously, I had anather ultrasound machine which broke. I cleaned more than a 1000 records with it, with no concerns at all. The machine broke and, due to its steep price, I decided to go for a less costly solution.
With the new machine I cleaned 7 records. One of themLeonard Cohen’s “New Skin for the old ceremony”. When listening to “Chelsea Hote”, I remarked a distortion that wasn’t there before. IT was clear on the low notes, like the instrument being out of focus or vibrating. I had some old very worn records which had that problem due to bad stylus. At first I started to think that there was a problem with the stylus of my Lyra Atlas. So I went to another version of the same album I have at home, to check if there was a problem with the stylus. Clean passage. No problem at all.
As on the previous cleaned record I noticed a similar problem, not so apparent, I decided to clean the second version of the LP on the new machine. Playing it i heard the same distortion on the same music. Checking out all the 7 records I cleaned, I heard issues on all of them, some less apparent ( the mono ones) and some more appparent.
I couldn’t believe it but the new machine was damaging my records.
The combination of my atlas and my SME 312 arm gives some “needle talk” - music heard when with everything muted you put your hear next to the stylus on the record. Doing it, I heard the same rumble distortion that was being amplified by the system.
I used distilled water (not a new one but one which was opened for the previous machine) but it was clear clean. I put the exact amount of surfactant liquid on the mixture of distilled water. I kept all the operating instruction rules. I don’t understand what is wrong, but the fact is this machines damages the grooves on the record.
Does anyone had this problem before? Any help provided?
Note: I already contacted the dealer who sold it and I am going to see him next week. It is a very good a solid dealer. It I’d like to hear your opinion.
Best regards,

The OP states 40kHZ and 60W output. The Humminguru website states output is 45W. Maybe it isn’t a Humminguru? I can understand the reticence about publishing the brand, but the worst of all worlds is to allow a brand to be falsely suggested as the culprit. Maybe the OP would simply say it isn’t the HG, but something different if that is indeed the case? |
If it was only the cleaned records sounding off, one can only explain this by wondering if they were not completely dry, or even whether psychacoustic factors came into play somehow? (I mean no disrespect with the latter, we are all susceptible.) Surely it cannot be a TT set-up issue or that would affect all records, cleaned or not. |
Yes one can be linked, but the file itself must be hosted elsewhere on the web. @antinn You remind me of something: the reason I bought a Loricraft many years ago was that I'd read the BBC was buying them to conserve their record collection. In those days if the BBC did it, it was a good recommendation. Not sure that is true any more! |
