[Tigers] Tach Help

[Tod Brown]

Tom Hall and Theo Smit have put together a wonderful bit of electronics, 
as others have said, to make the original tach in your Tiger work well 
and reliably.  If you need a tach with a bit more range, you can get one 
from a Series IV Alpine and use its face to replace the one in the stock 
tach.  The lettering on the face matches that on the MkI and MkIA Tigers 
and it reads to 6000 with a red line at 5500.  It looks correct except 
for the small lettering which reads 4 cyl, positive earth, which is 
hardly noticeable.  Only a purist or Jim Armstrong would object.  For a 
MkII Tiger, you can use a Series V Alpine tach to match the font.  The 
small lettering reads 4 cyl, negative earth.  You could probably get a 
rub-on numeral '8' to make it look even more proper.  The Series V 
Alpine tach reads to 7000 with a red line at 6000.  What makes the face 
switching possible is the board that Tom and Theo provide.  Using the 
PCB, they can calibrate your tach to read correctly with any of the 
above-mentioned faces, or they can calibrate the Alpine tach to work on 
your Tiger.  My Tiger has its original 260, albeit with a hipo cam and a 
Pertronix setup in an old Mallory YL dual point distributor, so 5500 is 
a nice, useful red line.
