I understand your pain. I have the same problem. Yesterday the shelf where my power adapter was on broke, it fell and broke. I quickly found a replacement on Amazon, but the prices are very high, and I can't afford that purchase. Now I'm looking for something similar in the Chinese online stores, but I'm afraid that what I buy will be of poor quality. To prevent such silly situations from happening again, I installed a new bar shelf and
hoop iron. I advise such a thing for those who decided to make a small repair at home. Please email me if you can find a store where you can buy such an adapter. Good luck with your search.
