Sure, you will learn what a 12V-220V inverter is able to do when one forget
to ground the coaxial link between preamp and an isolating transformer !
The inverter is used to charge the PC's battery and is only switched on when
the battery is low. So the beginning of the file is OK, and the end too as I
managed to ground the box which houses the transformer.
A side effect of the transformer is to cut the bandwidth below 8 kHz.
