28/56 Arcade Jamma PCB Edge Connector Solder Eyelets 56-Pin With Shrink Wrap Tubing Kit. This is a NEW dual row 28/56 pcb edge connector socket kit. We include 3ft of USA made flexible 1/8″ shrink wrap tubing so when your done soldering you can shrink wrap all your terminations. This isn’t that cheap import shrink wrap tubing that gets hard and cracks off over time; ours stay and doesn’t slide off. You can use these to replace your arcade edge connectors that have weak pins and not making good contact or make adapters.
