Repairs
Diagnosis, correction, verification.
Repairs begin with clear fault finding. Many issues in older equipment are caused by ageing capacitors, oxidised controls, cracked joints, relays, and tired protection circuitry.
Typical faults
- Channel dropouts and crackling
- Hum/noise and grounding issues
- Protection relay not engaging
- Overheating and bias drift
- Distortion at volume
Typical fixes
- Switch/pot cleaning or replacement
- Relay replacement
- Targeted component replacement
- Reflow of stressed solder joints
- Calibration and stability checks
