Collection: Pass Labs

Pass Laboratories, Inc. was founded in 1991 by Nelson Pass.  Operating out of his shop at home, Pass developed prototypes of a single-ended Class A amplifier design.  At the same time, he and Mike Burley were constructing an in-house machine shop with three home-built CNC milling machines with which to produce the amplifiers when the design was finished.
