Kenwood — Amplifier A-5j Manual
Ensure no stray copper strands cross over between the positive and negative terminals, as this causes a short circuit that can blow the amplifier's internal fuses or damage the output transistors. Troubleshooting Common Issues
The manual specifies grounding points. Ensure the turntable ground wire is attached to the screw marked "SIGNAL GND" shown on the rear panel diagram. Also, check the power supply capacitors (C901, C902) – the manual lists their values (often 12,000µF/50V) for easy replacement.
Fix: Unplug the unit, remove the top cover, and spray a small amount of electronic contact cleaner (like DeoxIT D5) into the volume control casing. Turn the knob back and forth 50 times, then let it dry before powering on.
