Don Classics U76A Compressor

Projects > Don Classics U76A Compressor

Building on the success of their NV73 500-series preamp, the latest offering from Don Classics is a 500-series recreation of the famed “Rev. A”/”Bluestripe” 1176 FET compressor. The U76A functions in the exact same manner as the original 1176, even down to integrated power conversion to the original +30V/-10V approach (while still adhering to the VPR 500-series +/-16V standard). It also features input and output transformers from legendary designer Ed Anderson. A PCB, enclosure, and switches are provided as a kit from Don Classics, while Hairball Audio offers most of the remaining parts (transformers, FETs, meter, knobs) in a separate kit. The rest of the components must be builder-sourced, but are easily attainable via Mouser.

U76A Features:

  • Same features/layout as original 1176, including “all buttons in” mode
  • Transformers recreated from originals by Ed Anderson

Price:

  • £149 for Don Classics “raw” kit
  • $155 for Hairball Audio parts kit
  • additional ~£116 in passive components
