Simple yet elegant and well built preamp from Conrad Johnson.

Gorgeous champagne gold faceplate with machined knobs. Great match to other Conrad-Johnson amps with a gold finish.

Zero negative feedback design which yields legendary Conrad-Johnson warmth and accuracy.

On the front you’ll find pure simplicity - just volume, balance, mute, and input selectors. On the back there are RCA inputs and outputs, and a fixed power cable.

Fully tested and working to manufacturer spec without any issues.

There are no noticeable deep or substantial scratches, just some light scuffs from typical use.

Includes just the preamp.
