HQaudios Restoration & Testing Process

Before Restoration

• After decades of service, the Kenwood KR-6340‘s power supply, amplifier section, FM/AM tuner, preamplifier circuits, input selector, volume and tone controls, switches, relays, and illuminated dial system require careful inspection before restoration begins.
• For this KR-6340, HQaudios places particular attention on the condition of the power supply, output stage, protection circuit, tuner section, controls, switches, potentiometers, speaker terminals, RCA input/output connections, and internal wiring. These components are critical to long-term reliability, channel balance, and overall audio performance.
• The amplifier circuits, tuner alignment, signal path, dial illumination, meters, and front-panel controls are also carefully evaluated to determine the receiver’s overall operating condition before restoration starts.

During Restoration

• Based on the inspection results, this KR-6340 was restored according to HQaudios’ technical standards while preserving the engineering and performance characteristics that have made this model a classic Kenwood two/four-channel receiver.
• The power supply, amplifier section, and signal path are cleaned, inspected, serviced, and adjusted to restore stable and reliable performance. Controls, switches, relays, and connectors are carefully cleaned to eliminate noise and ensure smooth operation.
• FM/AM tuner performance, channel balance, input selection, speaker outputs, tone controls, and all front-panel functions are tested and calibrated to restore dependable operation.
• The power supply, signal path, and internal circuit boards are inspected to ensure long-term reliability. Components that no longer meet technical specifications are replaced where necessary, while critical solder joints are reinforced to improve operational stability.
• After the technical restoration is complete, the exterior is professionally cleaned and detailed to preserve the KR-6340‘s original appearance while respecting the authentic character of vintage Kenwood equipment.

After Restoration

• Once restoration has been completed, this KR-6340 underwent comprehensive functional testing under real operating conditions.
• Amplifier performance, tuner reception, channel balance, output power, protection circuitry, meter response, dial illumination, and all audio inputs and outputs were thoroughly tested to ensure the receiver performs as originally designed.
• Finally, the unit underwent several hours of continuous listening tests through a complete vintage audio system to evaluate sound quality, operational stability, and overall real-world performance.
• Only after successfully meeting HQaudios’ restoration and testing standards is the Kenwood KR-6340 approved and prepared for its next owner.
