Sharp MD-DS8 for 280 yen - No Power - Can We Fix This Great MiniDisc Player with 1-bit Digital Amp?

The Sharp MD-DS8 is a nice-looking player and was Sharp's (the world's?) first portable MD player with a 1-bit digital amp AKA Sharp's Auvi/Delta Sigma amplifier. To get the maximum benefit you had to use Sharp's included balanced headphones or source your own 3.5mm balanced cable (not common). I'm a sucker for these quirky Sharps and I won this one on an auction for just 280 yen! Sure it was listed as not working and no power, but had to give it a shot for that price. Turns out it was a failure near the battery door hinge, but I did take it apart for a full clean and lube. Check out the video if you're interested since this player has a few tricks to take it apart. For the copper listed in the video, I used: Copper sheet roll 1000mm x 100mm x 0.1mm - https://amzn.to/3L8K23A Get the tools you need here: https://www.technicalinitiative.com/p...
