I do have a sort of DIY ultrasonic cleaner. I don't really know the Hz or how many watts it has. A local ultrasonic manufacture made one for me after I told them how big a bath I want. Basically big enough to submerge the whole LP with label cover. All I know is that it has 4 ultrasonic heads as the guy told me that I would need 4 for the amount of water capacity in the bath. It does a pretty good job in comparison to standard vaccuum machine but still a pain to have to take the LP out and use my record cleaner to dry the LP then use Furutech antistatic fan at the end.
For whatever reason, KLaudio unit which arrived a few days ago did a much better cleaning job than my DIY ultrasonic unit in less than half the time and is actually quite a bit more quiet. So my lesson is that not all ultrasonic bath are created equal unfortunately.
Now I have a giantic ultrasonic bath that is still really good to clean my glasses and wrist watch strap but not for my LPs anymore :)
