Thanks for the replies guys but I am confused. Are we saying there is a or some jones plugs in the back box that can alter the amount of credits per coin in each chute.As it stands at the moment I have a 20 cent mech in the 2 coins 1 credit slot so 40 cents per game. Middle coin slot gives 3 credits per 20 cents and the right slot gives 6 credits per 20 cents .All I want to do is change either the middle or right slots to give only1 credit per 20 cents or $1 depending on which coin mech I use.
