Looking at the schematic it shows a jumper and there is a note that says the jumper is not used on the CT version. Mine is there but it is cut in the middle.

If I had to venture a guess as to the need for the jumper it would be due to the fact that the cocktail version has more "general illumination" (lamps under the buttons etc...). With the jumper in, more load is expected (more lamps). In the upright case there are only the coin door lamps, so adding the load resistor keeps the voltage level at the appropriate level... :dunno

Got my package from Bob as well as my fiberglass pencil. Hooked up the new switcher, and while it doesn't make the loud noise that the old one did, it doesn't change what happens when I power on the unit.
So this weekend I will be cleaning contacts with the fiberglass pencil!

Now you don't have to be concerned with the PSU... an can just focus on other issues. ;)
TheShanMan:
So I've started working on the connector pins and chip pins with the fiberglass pencil. How do you know if you've rubbed the pins enough? I was assuming that it was abrasive enough that the pins would get shiny, almost like new. But that doesn't seem to be happening, so I wonder if what I'm doing is effective or if I'm not doing it long enough or something. Peale (or anyone else), could you perhaps describe in some detail how you use the pencil, how long you do it for, how you know that you've finished the job, or anything else that might help a noob?
