This a DIY kit for use in doing final debugging, addressing ground loops, and doing hum / noise busting in DIY Amplifier builds or repairs. This is very handy when doing final dressing of wiring and rotating a toroidal transformer for the lowest noise floor in your build.
Kit includes PCB, headphone jack, switch, diodes, resistor, banana plugs, and nylon standoff/screws shown.
You need to supply the wire from the PCB to the amplifier and headphones/earbuds.
