Bought a Buckwerx for an SST and it fits in the coin door, and disconnects the audio from the speakers fine and you can hear it in the phones. But, the volume is really low and the control on the buckwerx barely adjusts level and it seems the volume dial clicks on the wrong side, full open instead of click for full off.
Here are a few pictures, what do you think? This game has pinball pro speakers as well. To me it looks like the adaptor to the speakers is wired out of phase with the speakers?
