McIntosh MA5100 2-Channel Solid State Integrated Amplifier
The McIntosh MA5100 manufactured between 1966 and 1972, is celebrated as McIntosh’s first solid-state integrated amplifier. Combining a low-noise preamplifier and a 45-watt-per-channel power amplifier, it features the brand's classic gold-anodized and black front panel with illuminated teal-and-gold nomenclature. Key Specifications & Features Power Output: 45 watts per channel into 8Ω (stereo) Total Harmonic Distortion (THD): Less than 0.25% at full rated output from 20 to 20,000 Hz Frequency Response: 20 Hz to 20,000 Hz (± 0.5 dB) Damping Factor: 100Signal-to-Noise Ratio: 70 dB (phono), 75 dB (line) Tone Controls: Dual concentric controls with +18 dB to -18 dB adjustability Semiconductors: 34 transistors, 23 diodes, and 2 TRIACs
