Curtis, I used Theo's personal tach in my Tiger with the MSD6AL as a
test bed. It worked great, so I and Joe Parlanti, sent our tachs to
Theo to convert.
Theo used our tachs design to do further testing, so that it would work
with all types of ignition. That includes conventional points,
Pertronics, MSD, and Jacob's.
Joe and I now have out tach back from Theo, and although Joe's car is
still in resto, my new tach works great.
Finally a modern tach mechanism that is accurate, in my Tiger.
Thanks Theo.
Larry
PS - I also put another tach in the hole for a while, but didn't look
right, and never though it was accurate.
