Why does it say matched? Does this mean if one burns out you have to replace all four?

Matched means the four tubes are matched. If one burns out and you replace it you may need to adjust bias on tube. You use matched tubes so you do not need To adjust your amp when you replace tubes. Typically when one goes, the rest are soon to follow. So it is best to replace all 4

Would these tubes do well with a marshall dsl 40 cr?

These would be great for any amp that calls for EL34 tubes. Tube tone is subjective, so these may not work for everyone, but they are considered by many one of the most consistent and reliable tubes on the market.

Can you use these jj electronics t-el34-jj-mp vacuum tubes for a bugera g20 infinium?

The manual for the Bugera g20 infinium specifies a pair of EL34 tubes for the power section. So yes, these tubes can be used.

Turned my Blackstar amp on, and saw one tube glowing red, while the other is completely cold. Does that indicate a bad tube needing replacement?

That is usually the case..If it is the same type tube as the glowing one ..replace the cold tube in the socket with the good tube. That may help you figure out the problem..
