I finally got this machine in and it's my first Williams. There's a few fried coils and other parts that need replacement so I'm ordering that stuff now. There is a one-chime unit in the head made out of wood and it seems that is original to the machine from the little bit of research I've done so far. There's also a 3.5" bell in the head. Can someone confirm that this is the original chime/bell arrangement? In the '71-72 Williams parts manual it shows a chime box (B-6598) and says it is common to all games. If this arrangement is original then it's an interesting one with a combo of a bell and a chime but it does seem odd that there's only 2 notes so I may install a GTB chime unit which brings me to my next question. Can I jump off of the 10 point unit solenoid for example to provide a third tone?
Thanks very much.

thanks for all the replies, that's some good info for me to go on. i've finished going through the pin for a second time and didn't see any obvious issues other than a broken switch blade on the bottom of the cab and extremely hard to move stepper units thanks to solidified grease. the other thing i did notice is a small metal part that fits in between a stepper solenoid plunger and the arm it articulates with. it looks like it sort of cradles the arm and makes for a better fit between the plunger and arm and is what the tip of the pen is pointing to and a few are missing. anyone know what these are called?

@mbaumle-i have a copy of the manual on the way and I'll get in touch with Jay and see what he needs

thanks for posting that and that’s the part I was talking about. the bottom coil’s drive arm doesn’t show that part so I guess some don’t have it.

Latest is that I’ve removed and cleaned all the stepper units (some would not rotate at all from solidified grease), removed most of the parts from the playfield and cleaned it, and just received 3 coils to replace burned/shorted ones. Also ordered a backglass from bgresto which will ship with a Capersville bg I ordered awhile back for my neglected Capersville resto.
I liked the Williams style of horizontally placed switch stacks in the cab-makes for much better access as opposed to having switches on top of each other.
Received the owner’s manual which is the first em manual I’ve owned. Lots of great adjustment info and maintenance/lubrication data.

Obtained a GTB chime box, rebuilt it and wired it in but I kept the 1 point bell in the back box functional. Originally, this machine had two sounds-the 1 point bell and 1 small chime that was used for both 10 and 100 points. I isolated the switch in parallel so now 10 and 100 point scores each have their own chime. I did notice there is a high pitched ringing that accompanies each chime that sorta sustains for a bit. Anyone know how to mitigate this? It’s not unique to this machine, my Dimension does it too and it may be because I’ve been hearing chimes all afternoon with the playfield and coin door open that it seems more significant on this machine. I also measured the 1 point bell switch on it’s relay and was getting 30 (should be 24)volts so maybe the striker is hitting the bars to hard.
This pin sits on a wood floor so I made these feet out of sapele wood and sheet acrylic.
