History of UA’s 1176 Compressor

That same year, Bill Putnam is making the transition from the old standard vacuum tubes to new solid-state technology with his Universal Audio-brand preamps and compressors. The legendary engineer and equipment manufacturer had previously redesigned his original 108 tube microphone preamp (taken from his UA/United Recording consoles in Chicago and Hollywood), into the new 1108 — utilizing the recently invented Field Effect Transistor (FET). Subsequently, he redesigned his successful 175/176 tube compressor (based on the popular variable-Mu design) using FETs, and thus was born the 1176.

Bill Putnam was an absolute genius.
