Banana Jack

Banana Jack is a simple tool I created for connecting between eurorack modules and signal generator/oscilloscope for testing and calibrating modules. It's a bit little clunky but it gets the job done. There are two front panels to choose from. Either single or dual color. You will need:four pairs of panel mounted banana jacks such as these, max 20 mm deep behind the panel.four 3.5mm (1/8") panel mounted tele jacks, like these.wire to connect the jacks.The jacks can be connected with separate grounds, or with a common ground (as in the picture).
