Tech Hifi Audio Restoration

About this resource

Tech Hifi’s Mark Acoustics Lab services and restores vintage audio components and speakers from 1960 onward. It calls its approach “Restored as Original,” aiming for behaviour close to original factory specification and using factory service documentation as a guide. The workshop explicitly rejects rushed assumptions and indiscriminate replacement of parts as a default restoration method. ^[1]

The documented process starts by recording reported faults and visible defects, followed by physical and technical evaluation. A parts-and-labour quote is sent for approval, and no further work proceeds without it. Once approved, parts are ordered and further troubleshooting may reveal underlying problems. The page also describes extended audio testing to investigate intermittent faults, separating diagnosis from the subsequent restoration work. ^[1]

Intake is by first-availability appointment when the lab has capacity; it does not accept walk-ins or pre-schedule work. Its exclusions include automatic turntables, open-reel decks, home-theatre receivers, professional equipment and damaged or previously modified components. The page states a 90-day warranty on replacement parts and labour. The service-scope list and current intake notices are therefore especially useful entry points before assuming a particular vintage component can be accepted. ^[1]
