so i just looked into my amp and noticed that 3 of the tubes are not lighting up like the others do. the three of them are electro-harmonix 12AX7 and the other 2 are just say china 12AX7B. also y did the 2 tubes to the far right have some metal cup cover looking thing?

Those are preamp tubes, they don't light up like the power tubes do. How long have you had the amp for? As long as you don't notice a big difference in sound, I'd say your tubes are fine.

Not sure which is the Reverb tube, would have to check the schematic or manual. It should be a 12AT7 though instead of a 12AX7, that is if the reverb is tube-driven.

I've had tube amps for a while now, but never actually had any go down on me

maybe you're not saying the right things? an amp likes to know you care.
