Repair & Refurbishment:

On a selective basis, we offer repair and refurbishing services for vintage amplifiers and hi fi audio hardware. From a simple re-cap to a complete refresh, we will be straight-up with you about the viability of your hardware for refurbishment.

We repair and refurbish:

  • Analog audio electronics
  • Vintage vacuum tube hardware: Our bench equipment includes a tube tester.
  • Vintage guitar amplifiers: Whether for complete restoration or a simple electrical clean-up and recapping.

We can:

  • Validate performance and provide measurement data: Our bench rig includes an Audio Precision audio analyzer.
  • Complete loudspeaker and system measurements: Our toolkit includes a measurement grade microphone (Earthworks) and SPL calibrator (Bruel Kjaer):
    • Correctly scale measured SPL values.
    • Assess loudspeaker sensitivity.
    • Conduct loudspeaker testing out-of-doors in anechoic conditions. (Weather can be a factor in scheduling tests.)

(Please note: We decline to conduct full power testing or any testing of operating limits. This form of testing runs too high a risk of damaging equipment.)
