I played it a few days ago and it was absolutely fine!!
I turned it on today, no sound, i check all the knobs, the footswitch, no change. I tried different guitar, no difference, there's not even any type of buzz or anything coming form the amp, it's completely silent.

I turn it on, the switch ights up, the little lights for it turn on, but no sound or anything.

I opened up the back, and I noticed that the tubes aren't glowing at all, is this the problem? How do I fix this, and more importantly, HOW EXPENSIVE IS IT?

fuse blow?

Is it tube or solid-state?

if the tubes aren't glowing they are probably blown.

Tubes aren't expensive but like 40usd per a matched pair roughly, but getting someone to bias your amp for you might.

I don't understand how i blew them though, nothing really happened to the amp, I never pushed it at all in the last few days, I've been sick so I haven't played.

Sometimes tubes just blow, or other times its a different problem so if they blow again you know you have a bigger problem.

Okay so I finally bought new tubes (I've put it off because I was my band's bassist for the lngest time and i didn't think it necessary.)
I bought them at the store, he popped out all my old ones, put the new ones in, told me to plug in my amp at home, let it sit on for a few hours to let them warm up.
So I've done that, left it on since 5:30 today (it's 9:44 now) The tubes never lit up when i turned it on, and still aren't lighting up. I fear there may be a bigger problem.

If your amp stops making sound, the first thing to do is check the fuse. If it's blown then just replace it with one of the same value.

If the little wire inside the fuse is broken, you've blown the fuse. Read the value on it and buy a new one to replace it with.

If the fuse isn't blown, it's probably an internal issue.

Fuse is intact, the wire is whole.

The amp turns on, just there's no sound and the tubes don't glow. Is it the connection from my tubes to the amp possibly?

it may be a problem with your cords, i had a Tube amp and i swore up and down that that damn thing had a blown fuse...turns out my cable was frayed and i had to buy a new one...i wasted about 60$ trying to fix it, when it actually only cost around 10$....

man, that is a weird problem. ahhh, aside from a tube being blown, a wire not being properly soddered right or maybe even something to do with your guitars cable input...theres a plethora of problems that could be at work

The guitars input to the pickups could be soddered wrong (as i mentioned above). I owned a Epi SG that wasnt soddered right, yet again i blamed the amp, i took it to a music shop and they fixed it for about 50$.

As i said, theres plenty of things that COULD happen...its just a matter of time until someone makes a lucky guess and solves the problem

I have an RG50TC, and I can definitely say that it isn't a blown fuse, because if the fuse fail on that amp it doesn't even turn on. I recommend checking the tubes, and getting new put in by a professional if necessary, 'cause it's possible they need rebiasing.

I've biased the amp before with no problems. I put the old tubes back in and no luck. Going to drop if off to a specialist tomorrow to open the chassis up and take a look.

Gutted.
