I think my good, old Peavy TKO 115 combo of about 13 years has finally had it. One day while jamming, I totally lost all signal and a loud, staticy, hissing/crackling started coming out of the amp. I pulled out my cable and the crackling continued. I shut the amp off and didn't use it for a couple of days. I turned her on, immediately there was no crackling/static/hissing but once the amp warmed up it started again. Anyone out there ever experience something like this? Any ideas what it could be? Is it even worth fixing? I know I've got my money's worth out of it and it's been good over the years. Maybe it just bit the dust.
