 “REOPUS” = The REplacement OPUS Ignition Amplifiers have been manufactured since 2005.

The REOPUS 3 and 4 amplifiers replaced the Lucas OPUS amplifier circuit board in the  alloy case and used the original Lucas OPUS Pickup. Owing to increasing problems with the original Lucas OPUS pickup, manufacture of the REOPUS 3 and 4 amplifiers were discontinued in 2012. They have been replaced by the “REOPUS H Amplifier and "Hall effect" Pickup.  The REOPUS H system replaces both of the Lucas OPUS amplifier and the original Lucas OPUS pickup.

 We are happy to provide owners with technical support for the Lucas OPUS and REOPUS 3/4 and H ignition systems.
