tachometer amplifier

An original tachometer uses an amplifier , which is LV under the bonnet.

This has failed after many years of use, and due to low quality parts. 

With this new circuit board, your rev counter will work perfectly again, unless there is also damage to your rev counter itself or to the sensor, of course. 

This module is tested at the time I send it. You cannot send it back. After all, I cannot know what you will do with it afterwards.

The module is new and is plug & play.
