My ultrasonic cleaner was in the middle of a job, started to get loud, then made a PFFFT sound. I know it was the sound of death. It still gets power and the timer still works but it does not vibrate anymore.

So I guess the ultrasonic generator itself died. The most important component. I cannot think of a way to repurpose this thing. So I guess the question is, is it worth it to replace the ultrasonic generator? The answer to that likely depends on compatibility. What are the chances that another ultrasonic generator can be a drop-in replacement? Would they all generally take the same amount of DC or AC power, generally?

I am tempted to say not worth it, because the tub is small. If I get my hands on the naked UG component, I wonder if it would make more sense to epoxy that to a bigger tub, like a spare metal sink that I have.

BTW, it died under warranty and the vendor did not even want the dead unit back, so they apparently decided it’s not worth it for them to repair, and they would likely have the correct parts on hand.
