Well it seems it works for some but maybe not others. Any other tips and tricks people have picked up with working on these machines?
I get this noise hum on all of my A1up cabs and installed that ground loop noise filter on all of my cabs. Works like a charm. It’s because the audio output is being amplified from the PCB and not an external amplifier. If you are using an external amplifier such as the Logitech Z313 it will amplify the noise hum even more but the ground loop filter will strip out the ground noise. I highly recommend using an external amp.
An external amp plus the ground loop is a good call.
Hi mate, hope you are doing well. I picked up the Star Wars cab about a month ago when it went to £487 at Amazon and loving it. Just so cool using the flight yoke. Now it’s funny you just did this video. I had a really annoying hiss on my Pac-Man head to head, and put a ground loop on it, and the hiss mostly went but the sound comes out at about 50%. So I just have it at max, and can live with that. But I may try taking it off again as you did 😂. It may also have something to do with how close the speaker wire is to the power wire. On new cabs now I tape them well apart. I also have the static noise on the Marvel pinball and like you say it’s annoying once you know it’s there. May have to try what you did and see if it will go.
Ohh that’s a good price on the Star Wars. Yea the proximity to the power would make sense as a source of interference, must remember that. Worth giving it a go on the Pinball and see if you get the same results
