There are many ways to construct the back panel, and you may very well choose a different route.

As a very minimum, you will need:

• Audio input (from your record player)
• Audio output (to your amplifier)
• A ground screw together with the audio input

You will most likely also need:

• Power input connector
• Power button

Here's how I made my back panel.

I ended up working with plexiglass for the very first time. Let me tell you, that's no walk in the park. Unless the park is full of dragons and crocodiles and other things that makes you very cross indeed.

Nonetheless, I think I got the hang of it. Here are a few pictures. This first one shows my desk with a lot of clutter and a piece of plexiglass that has a power button, a 2.1mm power connector and the first two RCA plugs:

Here's a close-up of the back panel at this stage:

As you can see between the RCAs and the power button and connector, there's a hole for the ground screw.

Now, here it is completed (yes, I know, the ground screw is still missing):

The backside looks like this, with ground screw and ground cables:

There you have it. An input, an output, power and power button, a ground screw and ground cabling.

If you should wonder about the tidying up afterwards, it was almost as bad as working with plexiglass.
