Check the listing for details. Replacement Back Panel Power DC Jack Port for SNES Jr Super Nintendo 2 SNS-101. Condition: New. Listed at 14.07 USD. This is for a 3D printed back panel for SNS-101 Super Nintendo Jr or Super Nintendo 2. The DC jack on most SNES will break over time with use, this back panel replaces the DC jack and allows you to use a normal 9V DC Center Negative power adapter instead of the more expensive SNES power adapters. This also gives you peace of mind that you will have a much stronger DC connector and not the flimsy SNES power jack. The back panels available on ebay are only for the original larger Super Nintendo and not the Jr or Mini (SNS-101). This is 3D Printed in high quality PLA and comes with replacement DC board mounted jack. Please make sure that you have a 9v DC power adapter making sure that you have the correct polarity. The way this will fit in, you will need a 5.5x2.1 DC adapter with Center Negative. You will receive a 3D printed back panel and DC barrel jack. Feel free to contact me if you have any questions.
