So I pulled my play field out too far and coil hit speaker. since then my cabinet speaker has low volume. All connections are good. speaker ohm out at 4. I replaced it anyway. U50 and u51 2030 replaced along with u16 with same issue. I swapped ac/dc board into Metallica and sound is good so I eliminated wiring as being the issue. I’m assuming it’s on the sound board somewhere. U30 will be replaced next… anyone have this issue before? I am a newbie at this and components replaced by experienced techs. I have no answers from them. Very odd
