Kit containing all components to electrically assemble an Objective2 PCB: all standard resistors, capacitors, jacks, connectors, ICs, and circuit board. No battery, knob, or enclosure. Soldering required.
This kit contains all components necessary to build the Objective2 circuit board: all standard resistors, capacitors, jacks, connectors, ICs, and circuit board. No enclosure, batteries, or power adapter. Parts arrive individually packaged and labeled for your convenience. Soldering is required. All audio jacks are black as of 2014!
Assembly documentation can be found at NwAvGuy's Objective2 Details article.
Enclosure and Power
To completely assemble your Objective2, you will also need an enclosure, volume knob, and AC adapter. The following default parts are offered separately, as many builders choose to customize the assembly to suit their needs:
O2 Front Plate
15VAC Power Adapter
Aluminum Knob or Plastic Knob
You may optionally add 9V NiMH batteries and customize with different jacks as you desire. Components for optional modifications may be found in the DIY Objective2 and DIY ODAC categories. Please refer to documentation below for optional modifications:
