Slight Volume Drop

[lordofthethighs]

After I fire my Solo 50 Single Rectifier up, I play it for approx 10
minutes, and I get a slight drop in the volume. Also the bottom
end of the tone seems to drop out of it, by about 25% - 50%.

Any ideas what my problem could be? A bad tube? Maybe something else?

Any suggestions are welcome! 8)

... A bad tube? ...

yep...almost certainly. How old are the tubes? Probably best just to change them all, but if budget is a concern start with the power tubes.

Yup bad tube. Had the same thing with a ROV. Good thing is it only has two tube and relatively inexpensive to replace.
