It alters the frequency with which a kickout hole is lit for special, once that column of numbers is completed (i.e., the four different 1-4 sequences). All four numbers are still needed for each column.

For 5-ball play, the recommendation is for conservative, and for 3-ball play, liberal (IIRC).

(I'd have to go back and look at the schematic to recall exactly what it's triggering off for the frequency.)

On Kings and Queens, the hole frequency is not 1 to 4. The far left hole, lights like ever other 10 points. As you work your way to the right, the holes light less frequently since the right holes are fed from the left holes and it is more likely that you will fall into one of them while another special is lit. With never more than 1 hole lit at a time.

Looking at the Sing Along Print, it appears to be about the same with your jones plug lighting multiple holes at the same time. In fact, in the Cons. setting, there are three places on the 0-9 unit that no hole would be lit.Sing Along.jpg

If you look over on the right for the area contained within the dashed lines labeled 0-9 unit, you will see 10 possible pairs of dots. These represent the rivet heads on the unit. The double Arrow represents the wiper. As I recall, a Gott. stepper is 30 steps so those actual 10 dots would be repeated in order 3 times around the whole circle. However, you will notice that they did NOT label them as 0, 1, 2, 3 etc. like they did on the "Thousands Unit" or "Hundreds Unit" in the middle. That is because they are not actually wired in the order or pairings shown. It was done that way just to simplify the schematic drawing. So, those 10 dots are actually mixed around to randomize the lighting of the hole specials as 10 points are scored. The IN and OUT arrows are your Conserv. Liberal adjustment. When set to "OUT", you will see that 3 of the dots will never connect to anything (other than the wiper).

So, each of the three kickout holes (White, Red, Yellow) will light in 2 possible positions of the 10 steps of the 0-9 unit. This is increased to 3 positions if the jones plug is set to IN. The Green hole can only be lit at a single position no matter what the setting.

Just a tremendous explanation-thks Cactus Jack

I tried to explain how this works to someone once and i must say you did it much better than i did.
well done

Hey, I'm doing a full shop out of a newly acquired Sing Along, too!
