McIntosh MX113 // Vintage / Preamp Tuner / Fully Serviced (247H5)

The McIntosh MX113 is pure early-’70s Mac magic—a silky-sounding tuner/preamplifier that oozes warmth, weight, and that unmistakable McIntosh glow. With its beautiful glass faceplate, buttery-smooth controls, and rock-solid tuner section, it’s the kind of piece that instantly makes a system feel more refined. This one has had its power supply fully recapped, which is a big deal: it means quieter operation, better stability, tighter bass, and overall cleaner, more confident performance while keeping the soul of the original design intact.

Smooth, musical, reliable, and visually iconic, the MX113 is vintage McIntosh at its most inviting—and now, thanks to the fresh power supply work, it’s ready for decades more of effortless listening.

LINER NOTES

While all McIntosh components present unmatched value, the MX-113 is one of the best-valued McIntosh component of all time. It incorporates all the major design elements of the C26 preamp and MR74 tuner in a single chassis. With this 5th generation combo component, the engineers were able to quite successfully combine tuner and preamp, which is the type of innovation McIntosh is known for.
