What does anyone think using shielded wire to speakers.If it is possible for the speaker wires to get induced noise due to the magnetic field of all the other wire that surround them in the bundles of wires coming and going to the boards in back box.
My D>E> Laser War has this hum as well and isolation of sound board did not help. I just ordered the 30,000 mfd cap to see if that helps prob a waste of money but i can always use it some where else and have already recapped my sound board due to its age Just a thought

Thanks so much just ordered a power supply to try on mine Thanks for the detailed info

I did the exact same mod on my Laser War in it fixed it . I cannot believe how much better the music and call outs sound without the Data East hum Thanks for the info
