• Front Panel: There are bubbles on the front panel, some dirt inside the display, and slight rust on the mirrored surface.
• Product Overview: This McIntosh stereo power amplifier is designed to embody the policy of "better sound for longer" through unique innovations.
• Power Guard Mechanism: Equipped with a proprietary Power Guard mechanism.
• Self-Diagnostic System: The amplifier features a self-diagnostic system that automatically checks the circuit, divided into seven sections. If any issues are detected, the output to the speakers is automatically stopped until repairs are made, preventing damage from excessive operation.
• Custom Output Transformer: The use of McIntosh's specially developed output transformer significantly improves impedance matching and allows the power transistors to operate at about 20°C lower temperatures than typical amplifiers.
