Ultrasonic Cleaner Power Boost

[Steve Saunders]

I have a Sharper Image ultrasonic cleaner rated at 60w. I'd like to
increase the power to improve cleaning efficiency. Any hints, tips or clues
on how to do so?

Also, I'd like to attach the transducer to a larger container. Any clue on
how these are bonded to the tank? Epoxy?

Thanks,
Steve
