my head is only getting power from one of its two power tubes but both tubes are brand new. both tubes light up too, so i have no idea whats going on. HELP PLEASE!
i'm trying to see if i can afford to fix it or not.

How do you know only one of the tubes is working?
I don't give a shit if you listen to me or not

because the volume was maxed out and way too quiet for a 60 watt tube head. then the power tube cut in and the amp got twice as loud for about a second before it went back to being too quiet.

Well, first thing to check would be your cables, your guitar, and any pedals you're running. Try using a different guitar and a different cable and run it straight to the amp. Next, if you still are lacking volume then you probably need to replace the power tubes.

A site like the tubedepot.com, thetubestore.com, or dougstubes.com would be good. Let them know what kind of amp you have and they'll make sure the tubes are matched fairly close to your amps bias.
