Hi, I have a Ms. Pacman cocktail table that originally had a g07 chassis that was replaced with an aftermarket eygo chassis some time in the early 90s. Well, the eygo is dead, and I wanted to put a g07 back in so I bought an "as is untested" g07 chassis to try to refurb and put into the Ms. Pacman. The first thing I noticed was the posistor for the degaussing coil had been resoldered using a piece of wire because it had burned through the PCB.. So I desoldered the PTC and it rattles like crazy, my meter also jumps around a lot when trying to get a resistance reading on it so I'm thinking it's bad. I included a picture of where it burned through. I was wondering if anyone has a source for these?
Other than the PTC burning the PCB, the rest of the chassis looks decent besides being dusty as hell. Haven't found any broken solder joints, but I won't say there aren't any. I've replaced the flyback, and all the electrolytic caps with new except for the big c904 cap, and I was wondering what else should probably be replaced before I put it in the machine to test? The old flyback looked ok, no epoxy leaking that I could see but I found too many people who posted about blown flybacks after a cap kit, so I replaced it. I did test the HOT, but all I did was make sure it wasn't shorted to the chassis metal, F901 and F902 are good. I don't know if the x401 and x402 transistors are good, but they're not shorted. Also I did make sure that C302 was soldered in with the correct polarity. Oh, and I did have one resistor (R317) that was 4.7k ohms so I replaced it with a 390 ohm one and was wondering if there are any other problem resistors on the board?
The yoke wiring has the g07 connector back on it now so that won't be an issue. I still have to find an original video connector from the game, but other than that and the PTC I think I'm about ready to test. I've already discharged the tube and removed the eygo chassis.
Sorry if I'm asking too much, I appreciate any info I can get.
