Chaning capacitor to different value, ok?
 

The cap that goes in the tach circuit

"To eliminate noise/interference on the tach input we install a .1µF capacitor on that circuit as a filter. This eliminates random misses and allows you to use Hi-Res code successfully. "

I dont have a .1uf cap, and its a pain to get hold of just one cap and i could do with finishing this tonight.

I DO have 0.01uf caps and some 0.22uf caps and I also have a 0.1uf cap, but its rated to 35w. Are any of these any use to me?

I don't see a problem with the 0.1 uF 35 volt cap.

Excellenta :) Thanks
