Hi Guys-
I picked up a Touchmaster 7000, and it has what looks like a Wells Gardner 13K7201. The main board is labeled 'P757-D' the neck board is labeled 'P759'. Anyways, the chassis was disconnected, and I think that I figured out how everything goes back together except for a few things.
-The center terminal on the yoke does not have anything soldered to it. Is that a ground? If so, where does it connect to? See yoke.jpg
-The grounding strap around the tube is not connected to anything. Where does it go?See gndstrap.jpg
-On the main board, I can see a hole that used to have a wire soldered into it. What goes there? See p757d.jpg
-On the neck board, there is a piece of black wire that has been cut off. It is labeled 'CRT GND'. Where does that go? See p759.jpg
I looked at other posts as well as the monitor schematics and figured out how to connect everything up except for these last few things. Also, there's a loose black wire in the cabinet. I realize that all of the above mystery connections are all connected to each other somehow, but I'm just not sure how. I attached photos of each and circled the area that I'm talking about.
Thanks!
Rich
