Okay, the tubes on my champ are 30 years old and they are SHOT. I thought originally it was just the preamp tube, so I bought a new one, but I've now realized the power and rectifier tube are also gone.

What do I have to do to retube my amp? I'm still not really sure what biasing is and will I have to do it? My champ needs a 6v6 power tube, a single one, and a 5y3 rectifier tube. Now ideally, I want my champ to break up later but I'm not sure what tube to get for that. It's sort of annoying that I only need one and they seem to be sold in pairs.

These are the two tubes I was going to order for now though. Am I doing anything wrong?

I'm going to XC practice, but I will be back in like 2.5 hours.

Thanks for any help

I could sell you each tube you need, all vintage, if you would like to keep it vintage. I have tons of 6V6s, and some 5Y3s and 12AX7s laying around.

But if you wanted to go modern, I would go for JJs or Tungsols.

Also if your Champ is stock, you should be looking at replacing the caps too.

You can use a gz34 or 5v4 rec instead, for a little tighter bottom/mid and a wheedle more power.

Yeah it's silverface, I might try that.

Darkarbiter7, how much?

And how would I go about replacing the caps/how much would it be?

depends on which power tube you want (I only have one spare rectifier, so not much choice there). I can sell to you cheaper than buying new modern tubes.

If you have not serviced an amp before than this is going to be a tech job. Caps become 'leaky' over time and that means they aren't holding and supplying current as they should. This leads to the amp being quieter, and generally more flat sounding. I would suggest finding a local tech and having him do the tubes and caps at the same time. This will probably run you $200-300, including parts.

Yeah...see. I paid less than that for the amp. Maybe later. But I'm paying for college right now.

BUT I have build a small amp, repaired a couple hard wired ones and built a pedal.

Oh, well you are probably fine to go ahead and replace the caps yourself then. You'd have to get help from someone other than me, but AFAIK it's just a matter of identifying them (filter caps,) then draining them, removing them, and replacing them... Not much more difficult than any other soldering job.
