This CD player and matching DAC came in for servicing and repairs. The on /off switch on both had failed. There’s no spares available so a bit of ingenuity with some epoxy resin and away we go. I guess I could be printing new parts with a 3d printer sometime soon!
The tray on the Cd player was also faulty-a very common fault with these machines but then they are around 35 years old! New belts will be fitted and if that doesn’t sort it, the drive motor will be stripped and cleaned.
