Tachometer repair

Has anyone used the replacement PCB from Clocks4classic?

My tachometer has stopped functioning, so looking for a fix.
Smiths RVI 2402/04, been working ok for over 12 months with Petronix ign.
Thanks Les

Ordered the repair PCB, read the instructions and watched the videos (normally I don’t).
Fitted PCB and it worked.
Had to strap out the induction loop coil connectors and ran a new neg wire from the coil to the tach.
Just need to fit it back in the dash.

Hi just ‘bumping this tread’ interested to understand if others have repaired/replaced the original Smiths tachometer electronics with this replacement circuit board. Looks to be a sensible replacement if it’s reliable. Any further information appreciated.

Thanks
