	I've an older model Bransonic III ultrasound cell disruptor which has quit working. I can find no circuit plans anywhere, and am somewhat loathe to blunder thru it's innards randomly, although it is mostly discrete components rather than IC based, so I could conceivably do it, maybe. Anyone have any leads to where I may find either a circuit plan, or ?? any other advice? thankewverimuch, david

	I recall discovering that an ultrasonic sounder I was repairing was basically an RF Ckt feeding the RF to an Ultrasonic evice? Can this help? __________________ WARNING!

	I also recall having repaired a few Branson Sonifiers back in the day at MSDQ that were used to break-up some polymer I guess. And also some Sonifiers over at Harvy Hubbel. I am sure that each contained an RF stage just before the amp. The RF was injected to US device resulting in that peculiar sound that US devies make...annoying little things! __________________ WARNING! All suggestions are informative only.

	often the glue that holds the piezo element to the tank has failed and an air gap has appeared. Coupling drops to under 1%. Removel, clean and resilicone.. http://www.bransonic.com/ also e-mail them and ask. __________________ Per Ardua Ad Astra
