I bought an NVRAM WEEBLY sound board for my Bally Playboy, about two years ago. The board has been working fine for a few months and I did not use the machine for the past 6 months. Now, when turning it ON, everything works but the sound board generates a lot of background noises, like a rumbling. The sounds and various Playboy chimes and melodies are still audible, but the background noise is really obnoxious.
Everything else works perfectly on the pinball.
I was wondering if people have been having issues with these sound boards or if I am just the unlucky one. What would be another alternative to replace the Bally Playboy sound board, short of finding a true Bally sound board for that machine?
Thank you for your help.
