So i found this vendor sells convergence rings. https://arcadecup.com/ Anyone swap them out ever?

So when I looked the clamp, where can I safely manipulate the yoke assembly while it is powered up?

I suspected as much. On a positive note if i can sort the degauss issue, I can live with what I've been able to adjust to until I can find a suitable swap.

I went ahead and ordered a degaussing ring to test this theory further. The rings were marked, I assume by the factory, with a white paint stripe. As noted in the picture, one rings mark was misaligned. I tried returning it inline with the other marks which made the picture worse. I got the...

Just to verify wiring. Game is NHL Open Ice. This isn't the original monitor, or so i assume, since a u2000 monitor manual was in the cabinet with manual. Game is wired using - ground sync. I assume its correct as I get picture? The degaus is the ring that is routed behind/around the tube...

I cant say for certain on that. Im a rookie that hasn't encountered this before. *after thought. Thinking about your theory perhaps you're on to something. My othet crt games have an audible sound at power up. This powers up very quietly. Is that degaus cycle normally audible? That said I've...

Looking at convergence rings I can see from the white mark at least one ring has been altered significantly. I realigned the one off and see no improvement. Worse actually. The videos I saw discussed loosing the ring set screw and moving the stack fore and after. Is the screw directly center...

Thanks for the help. Ill watch some tutorials on that.

One more thing im noticing is when the display changes from a full screen image to another the overall image will shrink for just a split second and then return to normal size. Also when adjusting the screen pot on the flyback, the image size does change a bit vertically.

Kind of hard to show in a picture but this is the best image I could get. Also im seeing color changing on the top and bottom edges of the screen in color test. Its similar across red green and blue.

Monitor had bad flyback that took out the HOT. Flyback replaced, cap kit and new HOT installed. Monitor powers up fine. Now trying to get it adjusted. The image is sort of twisted counter clockwise. Ive played with all the adjustments on the remote board along with the horizontal hold on the...

Did a little cleanup and re-attached a resistor. After some testing it appears the transformer secondary 110v is bad. Gonna be interesting finding a replacement

Finally circling back around to a crane I picked up a couple years back for $100. The gantry returns to home as it should. The claw coil won't energize consistently and now it won't start a game. Pulled the relay board to investigate closer. Found a couple obvious issues here and there but the...

Who makes these? That looks incredibly useful

Im going to make an attempt to repair this amp. Any input or ideas on the symptom? Video with audio below. Amp Fault As soon as the amp is plugged in, it starts to make this terrible noise. Different amp in the same machine works fine. This amp worked fine until a storm that lead to a power...

🤔 So this and a jamma switcher, as well as an HDMI switcher or using separate inputs on screen, could be a viable option instead of a $500 Perfect Solutions Switcher?

I'm definitely going to dive into the schematics a bit more when time allows. I am far more knowledgeable with pinball machines than these monsters. I did pull apart the amp and do a visual inspection and some preliminary basic testing. Nothing jumping out. No burnt resistors, swollen/burst...

Yes. Have multiple cd100 units. Symptoms follow the bad amp

I wasn't clear, I don't have an issue on the mute circuit. I don't have a clue what it is/does. That question related to the idea of replacing the rowe amp with something else and how that would be affected. Unfortunately repair requires shipping the unit out to someone who works on rowe amps...

Random thoughts. Has anyone ventured to replace the cd100 amp with something different? Amp rebuilds are fairly pricey these days(~$350), significantly more than modern amps. What is haven't sorted yet is the mute circuit on the amp. I've skimmed the schematics briefly but haven't dove in deep...
