Hello lovro, the two boards are a touch switch (the aluminium strip on the front) to turn on the amp. Hi Joschi thank you for your comments, and yes indeed they were laser cut :P the funny thing is that I was in a hurry building this and I totally forgot to laser engrave the info on the back (inputs, outputs, etc) so I ended up burning in those dots by hand for indication :/
