Kirmuss 'In the Groove' Ultrasonic Record Restorer - Upscale Audio Edition

@larsman If the DeGritter isn't an US machine then why is it repeatedly described as such on the DeGritter website?

@terry9 What did I say that's misleading?

@orthomead 

I would not rinse with tap water. Tap water contains numerous minerals, hydrocarbons and a fluorine containing compound, typically either sodium fluoride (NaF); sodium fluorosilicate (Na2SiF6); or fluorosilicic acid (H2SiF6). All of these will contaminate the previously cleaned record surface. I would only recommend using distilled water for a record rinse. 

@jeffreylee - I don't know what you are reading; DeGritter is made in Estonia and it says this on their website:

We’re currently a team of 14, based in Tartu, Estonia, European Union. We operate on about 450 square meters, where we’ve put together machines for clients all over the world. Our space has an assembly room, a dedicated quality assurance room and a RnD area.

We like solving complex issues and we invest in our employees. We also have an internal kickstarter programme for motivation – who knows, maybe the next big Degritter feature or something totally new altogether will come from ther

@jeffreylee   "What did I say that's misleading?"

You said, "There’s no difference between the way US machines operate. Transducers create bubbles, the bubbles clean. That’s it."

That is so silly that you contradicted it in the next sentence. Then you ignore the fact that cleaning efficiency depends on both particle size and frequency. You also do not discuss the particle size usually encountered on records, and hence which frequency a record cleaner should use, and whether or not jewelry cleaners use this frequency.

You do not discuss power generated. Or power at the record face. Or distribution of power at the record face. Or QC. You do not discuss how closely the unit which has been delivered, adheres to spec.

You do not discuss the cleaning solution, type of surfactant required, rinsing, etc.

That do?
