I grabbed a PCB of WrestleFest, US version (Technos).
When the volume is set to more than say 10%, horizontal bars start to appear on screen. The loudest the sound, the more the bars are visible.
There isn't any problem with the sounds (no distortion of whatever) however the amp gets very hot if I turn the pot too much.
If I set the sound to a very low volume the game just plays fine (tested for one hour or so).
I've checked the documentation and the board only needs +12V and +5V (-5V pins on the edge connector lead nowhere).
