I'm assuming you have already determined it is the tach vs the tach cable.
If you are willing to take a used tach to get you back in the air sooner until a new one is available, perhaps eBay or Controller etc.
The Home page here has list of parts suppliers - click on International Comanche Society above and look in right column under the scanning eyeballs for the place to click. It has hotlinks. Air Parts of Lock Haven O/Hs a lot of the original Comanche stuff. I've had good success with virtually each that are listed - just takes work.
Hope this helps. Please post which path you take so we can all learn. Thanks.
