I am a noob to pinball but have been restoring my first pin a Gottlieb Wipe out. I am going to try and attach a video of my machine but it has this terrible BUZZING sound. The sound is pretty constant and will sometimes get better for a short period of time. I know I’m a noob but I thought I’d ask the many pinball geniuses out there if you could please help me diagnose this issue! Thank you for your help!
