Thanks a lot for the replies, I guess I'll try a tube change and see if it solves the problem. Regards

My DT25 head has started blowing the tube protection fuse. This happens shortly after i turn it on. I have noticed the following before it happens: 1. I turn on the amp. 2. wait for a minute or two. 3. The amp starts making crackeling noice and one of the power tubes starts glowing brightly (like it has a hot spot all orange) If I don but it in standby at this spot, then the fuse blows. Do I have a faulty amp or do I just need to replace the power tubes ? Any help is greatly appreciated.
