Hmmmm LSC power loss?

[guitar99]

So Ive been running my lsc in a jazz/blues project at 10 watts, and in tweed mode....
Last night, it dropped power drastically in the clean channel ( I use the dirty for leads here and there but it didnt change )
It pretty much disapeared..

Now when I set it to normal instead of tweed, or went to the 50watt, it stopped and went back to normal?

Tubes should be in good shape, not that old, but we all know how that goes...

Opinions?
Ideas?
Baking tips?

Come on guys, no one has any idea?

Your description is a little confusing, honestly. It's hard to tell what's happening.
Was this a one-time occurrence?
Only on Tweed?
Only on Ch1?
"Pretty much disappeared" meaning... completely? Or not?
Was it while you were playing, or when you first turned the amp on?
The tubes "should" be in good shape? Did you... try other tubes?
Have you experimented with the other settings, verified whether your FX loop was on or off, Send level up, etc etc etc.?
