Bare printed circuit board for the Objective2 headphone amplifier. PCB is electrically tested! Objective2 is an open source amplifier designed by NwAvGuy, with emphasis on benchmark performance and low cost.

Please refer to NwAvGuy's Objective2 Details article for the bill of materials and assembly resources. You are responsible for obtaining all components and assembling the PCB. JDS Labs provides no support for the Objective2 design.

E-Testing: We require electrical-testing of all of our PCBs. Many DIY circuit boards are not e-tested, leaving a 1-5% chance of circuit defects. E-testing slightly raises PCB cost, but tested boards ensure problems are never caused by the circuit board itself!
