Dried-out electrolytic filter capacitors in the power supply. Inspect for bulging caps or leaking electrolyte. Comprehensive Guide to the Bell PSX-6022 Power Amplifier:
| Issue | Reported Cause(s) & Suggested Fix(es) | | :--- | :--- | | | Diagnosis : Burned-out 10-ohm resistors (R03, R103) on the input board are a common cause. Suggested Fix : Replace the burned components. Also check the source signal voltage, as excessively high input voltage is a suspected cause. | | General Failures & Unreliability | Diagnosis : Some users report a general lack of reliability. Suggested Fix : Thoroughly inspect all internal connections and look for cold solder joints. The build quality is sometimes noted as "rather poor," making a comprehensive inspection worthwhile. | | Output Transistor Failure | Diagnosis : Short-circuited 2SC and/or 2SA series output transistors are a reported failure mode. Suggested Fix : Replace the failed transistors. Also check the surrounding passive components (resistors, diodes) and consider verifying the bias settings if you have the expertise. |
