Description from the seller
McIntosh MC30 Monoblock Tube Power Amplifier – The Golden Age of American Hi-Fi
For sale is a well loved McIntosh MC30 — one of the most legendary vacuum tube monoblock amplifiers ever built. Manufactured by McIntosh Laboratory Inc. in Binghamton, New York, between 1954 and 1962, the MC30 represents the pinnacle of mid-century American audio engineering.
Renowned for its lush midrange, holographic imaging, and silky smooth high frequencies, the MC30 has become a favorite among audiophiles, collectors, and recording engineers seeking that unmistakable vintage McIntosh sound.

The MC30 delivers that unmistakable warm, musical McIntosh tone — rich in detail, with a powerful, three-dimensional presence that modern amplifiers rarely replicate.
A truly collectible piece of hi-fi history, perfect for pairing with vintage preamps or high-efficiency loudspeakers.
Please see the pictures of the insides for an idea of what work was done.
