tachometer
 

I am having constant problems with my dual tach. Keep rebuilding the front mag tach points, etc. Erratic readings (as checked with digital handheld)


Sometimes is settles down after a half hour or so of flying, so no realy identifiable problems.

Does anybody make a dual digital tach that I can put in as a replacement?

Also I have a very good working dual fuel flow gauge (replaced it with a digital computer) that I will let go for whatever is a fair price.

80-337H

Yes , Roger!!
I have Electronics International dual tachs & Manifold P in my 67TB and they are awesome (Previous owner installed) You can line your engines up easily and you do not have to interpolate those bouncy needles...I like them so much that I must install them on my 74P I recently acquired. I have not seen another 337 with them installed....JIM

Jim,

Thanks!
