Audio Desk Record Cleaner

Does anyone know what frequency transducer the Audio Desk record cleaner uses?

How can you tell if the transucers are working as I see no bubble action in the water bath as the record turns?

JWM, seems to me, you can tell that the transducer is working based on the physical and audible improvements after cleaning.

After listening to a few noisy albums at your house before cleaning, then hearing them after cleaning, everyone in the room agreed, there was a HUGE improvement. Not only that, the albums looked so shiny and squeaky clean!

My only concern, after washing several dirty albums, seems like the water in the holding tank would get pretty nasty, contaminating future albums being cleaned. I guess there's supposed to be a filter inside but I'd like to see more info on how it works and how effective it is.

I top it off with distilled water alone on the theory that the cleaner concentrate is not supersensitive to the precise amount of distilled water in the tank.

Hessec,
Not to downgrade your fluid mixture at all, Pepsi admits that Aquafina is just filtered tap water.
