Hi!

I'm quite a newbie when it comes to electronics, but I have a friend that knows more than me that is helping me figure out what is causing a 0.2 volt spike on the audio output of this keyboard.

Does anyone know if a voltage difference on the power supply could be causing this thump? I'm measuring 11,9 negative and 11,6 positive voltage over the capacitors c39(-) and c38(+) to ground. The audio output is registering a spike of around 0,2 volts. Is this purely coincidence?
