PROFESSIONAL RECORDING STUDIOS
ATR Service is best known for detailed restorations of the Ampex ATR-100 Series recorders. Our restorations are more detailed in construction and accuracy than were possible or practical at the Ampex factory. We take great care not to alter the exceptional sonic qualities of the best tape recorder ever produced. We do however improve the build quality and incorporate a number of reliability modifications as the original models were subject to a number of related failures.
