For 385.00 for a new one I thought I might see if anyone had an extra one lying around they might want to part with. Part#3010005 RPM xducer,slick,tso-c113. For my RV-6A. Contact me/ Bill Marcum at 361-549-9567 Corpus Christi,texas
 
Can you post a picture of your old one? What engine/mag combination do you have it on? I have an extra RPM transducer, magneto type that looks like it screws into the case.
