Up for sale is a single, premium New Old Stock (NOS) RCA 35120 Germanium NPN transistor from 1969. This component was built to rugged military/mainframe standards for a UNIVAC computer project, offering far tighter tolerances than consumer-grade audio parts of the era.This individual unit is an absolute "unicorn" find for boutique pedal builders and DIY enthusiasts looking for a high-gain, clean-testing NPN germanium device.

  • Custom NPN germanium boost or preamp projects

  • Type: Germanium NPN (Negative Ground Friendly)
