J79-11a RPM gauge

Well I had an interesting thing happen on the NAE. The RPM gauge died, the tach drive is and so is our backup unit. I opened up the gauge and pieces fell out, the reluctor grenaded and tossed parts into the little itty bitty electric motor and broke other things. I just goes to show you cannot purchase used instrumentation and expect it work for very long. We installed our spare and it has troubles. I guess it's back to the ebay stores and find some more used? junk maybe I will find a couple that can be rebuilt. Buyer beware!

These are pretty universal. Any off a Bell 206 helicopter or MA1A Start cart will work too. If you can't find one asap, I have a couple.
