    Lab12 Mighty Class A Power Amplifier

    The Lab12 MIGHTY is a Class A Single Ended Power Amplifier that takes EL34. 6550, and KT88 tubes. The MIGHTY outputs approx 10 watts (tube and mode dependent). Also the user can easily switch between ultra linear and triode mode and the MIGHTY is fixed bias by design.

    Lab12 believe nothing comes closer to the sound of pure Class A, single-ended audio amplifiers and they’re pushing the limits again with MIGHTY, which encapsulates all the best attributes of refined tube designs along with the emotional impact of true Class A.

    MIGHTY cuts through the layers of music with ease, offering total control and the ability to deliver music in the best possible way to any speakers.

    MIGHTY was designed from the ground up to work in perfect synergy not only with all Lab12 Preamplifiers, but also with all solid state and tube preamplifiers on the market.

    Lab12 designers have spent countless hours listening and incorporating the finest selection of audiophile grade electronic components to bring music lovers a one of a kind immersive listening experience that ensures many hours of fatigue-free musical enjoyment.

    As with all Lab12 products, Mighty comes with a glass blasting anodising finish (in black only).
