Funny you should ask that.
We were given an ultrasonic cleaner last week that does not work.  I have
it planed for one of my students to open it up tonight and start
troubleshooting it to figure out what's wrong with it.
I had to double check you're email address to see if the question was a
prep-question from the student who will be doing the work :-)
We'll take some pictures for you so you can see inside one.
