I am selling my McIntosh MC7270 power amplifier in very good, fully functional condition. The unit is in great shape both optically and technically: the glass front is flawless (no "bubbling", no cracks) and scratch-free. The chassis shows minor signs of use, but none on the front. It comes from a well-kept, non-smoking household and has been thoroughly tested.Technical SpecificationsType: Stereo Power Amplifier (Solid State) Continuous Power (Stereo): 2 x 270 Watts at 1, 2, 4, or 8 Ohms Continuous Power (Mono / Bridged): 1 x 540 Watts at 2, 4, 8, or 16 Ohms Frequency Response: 20 Hz – 20 kHz (+0 / -0.25 dB) Total Harmonic Distortion (THD): 0.02% (at full power, 20 Hz – 20 kHz) Intermodulation Distortion: 0.02% Signal-to-Noise Ratio (SNR): 100 dB Damping Factor: > 30 Input Sensitivity: Switchable between 0.75 V or 2.5 V Special Features: McIntosh Autoformers, Power Guard circuit (prevents clipping), Sentry MonitorDimensions & WeightWidth: 41.1 cm Height: 18.1 cm Depth: 36.8 cm Weight: approx. 37.2 kg (Net)Condition & Scope of Delivery:McIntosh MC7270 (Serial Number: 42607) Power cable (fixed) The original screw terminals have been fitted with high-quality banana plug adapters for better handling (see photos).Important Shipping Note: Since the original packaging is no longer available and the device weighs over 37 kg, shipping from Sweden will be handled exclusively via freight forwarding on a (half) pallet. I will construct an extremely stable transport box made of wood and reinforced foam to protect the sensitive glass front and the transformers. Shipping costs and insurance details will be coordinated individually.
This US$3,738 asking price sits right at the median of the typical used market for the McIntosh MC7270, which generally ranges from US$3,500 to US$4,000 for working units, making it a fair deal rather than a bargain. While non-working or lower-tier examples can appear around US$1,500 to US$2,000, a clean, very_good condition unit commands this higher valuation, so the price is honest but not especially aggressive.
The MC7270 remains a worthwhile buy because it delivers 270 watts per channel with McIntosh’s legendary autoformers, offering exceptional reliability and tonal warmth that solid-state amps of the 1985–1991 era rarely match. Its 270-watt power is a significant upside for modern high-efficiency speakers, and the very_good condition suggests original-owner care with likely minimal wear, making this a solid buying opportunity for enthusiasts seeking vintage McIntosh performance without the risk of a faulty unit.
