I was wandering if any of you guys could help me with this.
The fan from my marshall MG50 makes a buzzing niose when i turn it on as if something is stopping it spinning properly. I tried removing the guard and cleaning the dust from it which worked for a while but the noise returned. I tried cleaning it again but it didn't work at all this time and the noise is worse than ever and it sounds like it isn't doing itself any good. Anyone got any ideas on what the problem is?
