Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

Super neat step-up transformer built in Japan during Denon's best period and utilizing the best components available at the time.

This is a step-up transformer meant to increase gain so you can utilize a low output MC (Moving-Coil) cartridge on a MM (Moving-Magnet) input.

No RIAA EQ included, just additional gain.

In very good condition with little signs of use. Working perfectly after testing in our lab.
