Repairs
Diagnosis, correction, verification.
Repairs begin with clear fault finding. Many issues in older equipment come from 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 and pot cleaning or replacement
- Relay replacement
- Targeted component replacement
- Reflow of stressed solder joints
- Calibration and stability checks
