Alles anzeigenFirst of all, congratulations on the Bootleg Cabinet, you don't find it as often as the original.
There are very different versions of this, even a sitdown version...
Regarding your problem with the sound.
An audio amplifier is installed on the board and requires 12V DC.
On my connection pictures you can see where the speakers have to be connected and the +12V and GND should also be present on the same plug.
So first check whether the speakers are wired correctly and measure the 12V with a multimeter.
Then there are the 2 potentiometers with which you can adjust the volume for left and right (red arrows)
Yes, I will try to find a way to connect it to a monitor on my desk. The part on my board has been most affected by moisture.
