We have a lovely Williams Grand Prix circa 1976 and I’ve been restoring it to full working order over the last year or so. Couldn’t believe it the first time I lifted up the play field and saw the circuit diagram
Everything is (almost) working now, however the right hand kickout (I think that’s what it’s called) actuator is too powerful and the ball always hits the glass when the ball is ejected. The left hand one is good and is just the mirror image of the RH one. I’ve compared the two and the 2 coils, springs etc. are the same. The operation of the two mechanisms is the same with no binding, same spring resistance etc.
Any ideas as to the best way to reduce the power of the RH one, without compromising the function or reliability? I thought of adding an inline resistor to the coil circuit to increase the resistance and therefore reduce the power - what do you think?
Or am I missing something?
Any help would be much appreciated.
