Amp head Burning smell, speaker hum….
So I use a Mesa boogie filmore 100 head. I just got the filmore cabinet. I used to use a 4x12 roc pro cabinet. I have 2 of these exact same mesa heads. Tonight while playing I smelled this burning smell coming from the amp and then it started to hum. I was getting this popping sound when hitting the standby switch. The kind of sound you get when the standby is off and you accidentally turn the guitar amp off. I thought it was an issue with the head so I tried my other head and it’s doing the same thing. It also feels like the amp is overheating in a way… any help would be greatly appreciated!
