Here's a classic piece of audio gear for the discerning listener—a Denon AU-320 step-up transformer in great working condition.

If you're running a moving coil cartridge and want to pull out all that rich, detailed sound without breaking the bank on a super high-end phono stage, this little silver box is a game-changer.
