Upon its release in 1967, the 1176 Limiting Amplifier became an instant classic because of its unique lightning-fast attack and release times, musical Class A output stage, and its wide range of sounds, ranging from subtle, near-transparent compression, to all-out drive and distortion.

Universal Audio’s 1176LN Classic Limiting Amplifier is a handbuilt, faithful reproduction of Bill Putnam Sr.’s original visionary design — an iconic piece of audio history that had a hand behind classic recordings from Led Zeppelin, The Rolling Stones, Michael Jackson, and more.

The Unit

I've had this unit for some time and whilst I've fully tested it and everything works well as expected I'm some marks and tarnishing reflecting useage and the unit being more than 10 years old now. The meter does seem to zero fine however I've never had this unit calibrate and as such I'm selling te unit verymuch as is and on the basis that it could do with a calibration is that is something you would normally periodically do with your compressors.
