Hello. I'm new here. I've been having some issues with my Mesa Mark IV for a little while now. I've called Mesa and searched constantly to figure this out, but it doesn't seem that I will find a solution to this.
A few weeks ago, my amp was making random noises every once in a while, sometimes it would get bad. Not sure if it was an unshielded cable causing that or what. I also noticed that one time it got really bad sounding and I turned it off, and happened to look in the back. The power tubes were glowing extremely bright. I think it was "red plating"?
Fast forward to my next show. We played our set and on our last song, towards the end. The amp loses volume, then completely dies on me. (Lights and everything). The next day. I changed the fuse, thinking it was the venues power that blew out my fuse.
I found a replacement, and proceeded to practice on the amp. About 30 minutes in. The amp shuts off again. I check the fuse, and it is blown again. I then read up that it is most likely caused by a power tube failing. I went and bought a new fuse and 4 new Mesa 6L6 tubes. The only problem I have now is.. I'm sort of afraid to use it because when I turn it on full power. A few of the tubes start getting bright.

Do these look normal, or are they "red plating"? I think I might be a little paranoid.
On a side note. When I use my amp in Tweed power. It looks "normal" to me. No bright plates.
What do you guys think it could be?
