HQaudios Restoration & Testing Process

Before Restoration

• After decades of service, the McIntosh MC2205’s power supply, power amplifier circuits, output stage, Power Guard circuitry, driver boards, protection circuits, speaker terminals, input connections, and illuminated watt meter system required careful inspection before restoration began.
• For this MC2205, HQaudios placed particular attention on the condition of the power supply, output transistors, driver stage, Power Guard circuitry, Autoformer output stage, protection circuits, input/output connections, speaker terminals, and internal wiring. These components are critical to long-term reliability, power delivery, channel balance, and overall audio performance.
• The amplifier circuits, signal path, illuminated watt meters, Power Guard indicators, front-panel controls, and protection system were also carefully evaluated to determine the amplifier’s overall operating condition before restoration started.

During Restoration

• Based on the inspection results, this MC2205 was restored according to HQaudios’ technical standards while preserving the engineering and performance characteristics that have made this model one of McIntosh’s most respected vintage power amplifiers.
• The power supply, signal path, and internal circuit boards were inspected to support stable and reliable operation. Components that no longer met technical specifications were replaced based on inspection and testing results, while critical solder joints were reinforced to improve operational stability.
• Power output, channel balance, Power Guard operation, meter accuracy, protection circuitry, input sensitivity, and all amplifier functions were tested and calibrated.
• After the technical restoration was completed, the exterior was professionally cleaned and detailed to preserve the MC2205’s original appearance while respecting the authentic character of vintage McIntosh equipment.

After Restoration

• Once restoration was completed, this MC2205 underwent comprehensive functional testing under real operating conditions.
• Power output, frequency response, channel balance, distortion performance, Power Guard operation, watt meter response, protection circuitry, and all audio inputs and speaker outputs were thoroughly tested.
• Finally, the unit underwent several hours of continuous listening tests through a complete vintage audio system to evaluate sound quality, operational stability, dynamic performance, and overall real-world performance.
• Only after successfully meeting HQaudios’ restoration and testing standards was this MC2205 approved and prepared for its next owner.
