Several years ago, I used to buy surplus electronic equipment from
an outfit called Meshna Surplus. They're located in Lynfield,MA.
Does anybody have the complete address and/or phone number of this
company.
Also, does anybody know of a good source for ultrasonic transducers.
I'm looking for something in the >30kHz range capable of handling 
a reasonable amount of power (the disks used on the underside of 
ultrasonic cleaners would probably be fine).  They would be in use
continuously so I'm not sure if a hydrophone type unit would do (I'm
not really to clear on hydrophone operation).  Size should be less than
6 square inches.  Any information/suggestions/advice would be greatly
appreciated.
      
                                    Thanks in advance
