Standard 7-part Amplifier Service schedule:
- Visual internal inspection: Inspected for leaking smoothing capacitors, signs of overheating, and obvious historical tampering.
- Note: this amplifier is hardly a vintage amp so did not require the knobs and switches cleaned, its only amplifiers of a more vintage age that need this. (Our service for amps of a more vintage age include: Push buttons and rotating knobs/switches cleaned: All front push buttons and switches cleaned with Deoxit and re-lubricated for long lasting protection against crackling and channel dropouts.)
- Audio input Path cleaned: All RCA inputs cleaned ready for use
- Audio input Path Verification: Primary fixed analogue RCA inputs and front-panel output headphone socket/potentiometer fully tested for balance and pristine signal purity.
- Digital section checked: coaxial and digital intputs checked for sound if fitted. N/A on this particular model.
- Thermal Soak Run: Unit stress-tested for continuous use for a minimum of 2 hours to guarantee long-term component stability.
- * Final Electrical Safety Check: Mains lead and internal fuse ratings verified for safe domestic operation.
