| Amp making crackling noise
Sign in to disble this ad
I have a SWR WorkingPro 2x10C. Have had it for several years and have had no problems up unitl a few days ago. Now when you power the amp up, it makes a crackling noise for several seconds and then stops. The amp sounds fine once the noise stops. When you turn it off it does the same thing. It will occur with or without a signal cable inserted so it's definitely within the amp. Bad cap(s)? |
