I just had to do this on an old chassis so I thought I would document it
1. This guide assumes you already have the chassis safely removed and are still alive (See here if you need to do that first)
2. If you are getting arcing on your monitor, or you anode cup is cracked, damaged or just in-flexible, you can easily replace it yourself
3. We suggest you remove the chassis and do this on the bench, so solder doesn't drip into you other arcade components in the cabinet
4. Here is the chassis I will do the demo on (LAI BW Vector Monitor) LAI-KZ-20XYB
(Click to Enlarge)

5. Next thing to do is find a cup in good condition to use as the replacement
6. Here are 2 options off old TV Chassis' I picked up off the side of the road


I chose the 2nd one as it is closer to the physical style of the LAI chassis' cup
7. Next step is to slide the old cup off, without damaging the insulation of the lead. You want to keep the lead as long as possible. I used some of this WD spray to make it slide easier.

First you pull it inwards, cut off the spring, then slide it the other way, off the end
