I know its k7000 series, but its a little different. I replaced all the caps (except for the one on neckboard).

But it has that little daughter card ontop thats not connected to anyting..

wells

7191 or 7193 or some other 7190"s
i have seen so many 7000 wells with a part or two added here and not there,jumpers added, from chassis to chassis with the same model number in the same games that i called way back when and they said they like to tweak things to make them better. Not a great answer so now i just fix them now and dont worry except when i deal with wells 4900's when people switch chassis because i did run into problems with Well's jumpering and tweaking as they have different chassis's with the same number that have a scanning problem when you switch from one tube to another. Usually you got lines on the top of the screen and could not get rid of them.
Thats 20 years ago so the mind is going.
