| It could be the rectifier tube. I had a '95 Korg reissue ac30 and the same thing
happened to me, about six times. I kept taking the amp back in to my amp guy,
I'd get it back and it would be fine for a couple of weeks, then it would start
blowing the same fuse again, the one inside the chassis. I finally got tired of
dealing with it and sold the amp. After doing a little research, I found out it's
a common problem with these amps. If you do a search for Nashville Amplifier
Service, I think they have a mod that fixes the problem. Maybe you could find
a tech near you to do the same thing. |
