Frankly, if you could score a known-good amp or amp-guts for a few bucks, it would be a lot easier. It is good to learn to fix; but all fixing is about
playing, and a 10-buck 11-screw fix beats hours of frustration and possible damage.

rescues orphan squirrels, and has shipped me
a huge glass tube which arrived intact. He seems like a good and careful guy. But I agree that a teenager should not be dealing with strangers. And while it looks like an easy swap-out, I know (too well) that it is possible to foul-up "easy" swaps.

huge amounts of white noise.Pure HISSS? Not hum? Buzz? Whine? Throb?
Did it do it from new? From when you got it used? Did the hisss start recently?
Your guitar is good?
You have tried with no effects pedals in the path?
Do the controls have any effect? Which control? What effect?
What have you done to try to fix it?
Most hiss can be reduced. But sometimes it is NOT easy. I spent too much of my life on similar work. It is hard enough when you can touch and poke and measure, much harder to collaborate through cyberspace.
I'm dubious about the LED. Can you point to where you saw that suggestion?
A lot of questions; but this is what I'd want to know when a hissy amp was dropped on my bench.
