McIntosh MC2105 // Vintage / Solid-State Amplifier / Electronically Restored (AH2602)

The McIntosh MC2105 is one of the most beloved solid-state classics in the Mac lineup—those iconic blue meters, the glass faceplate, and a sound that defined an era of American hi-fi. Delivering 105 watts per channel with that unmistakable McIntosh smoothness, the MC2105 is known for its rich midrange, unfatiguing highs, and bass that’s warm, confident, and wonderfully musical.

This unit has been electronically restored, including the critical replacement of the large filter capacitors, giving it the stability, punch, and low-noise performance it deserves. With fresh power reserves and updated internals, it plays with greater authority, clarity, and ease—while retaining every bit of that classic Mac character.

A beautifully revitalized piece of hi-fi history, ready for decades more of those soft-glowing, blue meter-dancing nights.
