[Healeys] Tach rebuild

[Bob Spidell]

FWIW, I’ve had a Pertronix in my BJ8 for almost 20 years and my tach works fine. I did calibrate it once with the internal trim pot.

I know it is not the clutch slipping.   I saw some articles in Healey Marque magazine showing how to rebuild and test them, but it requires a oscilloscope and some other specialized equipment I don't have, so I'm wondering if you guys have a recommendation for someone that might rebuild them.
