Pass Labs
Foresthill, California
United States

Pass Laboratories has hand assembled commercial amplifiers and pre amplifiers in Foresthill CA for 21 years.

All are personally overseen by Nelson Pass. They are all unique in some way - some are current sources, some have no voltage gain, some have only one stage, some use power JFETs, some use feedback and some don't.

Nelson and co-designer Wayne is a large supporter of DIY audio and frequent contributor of projects directed at the electronics and audio hobbyist.
