Your amp is very very angry with you.....

In all seriousness, check the fuse, and open the back and check the tubes to see if any are blown.

It'll often look blackened or broken, though with some you may not able to tell. Buy a 5 pack and replace it anyway, tossing the old one in the trash so you don't confuse it. If that fuse won't work, try another to make sure the new one doesn't have a fault. If it's still blowing fuses, it's likely a power tube failed.

ok, lol, there all in tact from what i can see...

The bottom of the tube is normal. Your fuse should be on the pack somewhere, by the power supply.

ok ill check it out. i couldnt beleive the tubes were broken cause i bought the amp like 2 months ago. i was reading about tubes and they should last for a while.

same thing happened to me a few days ago. blew two fuses....one was for one of the tubes, and the other was for the power supply.

annoying part is that the one for the power supply is a 3A 5X20mm slo blo that doesn't seem to be in ANYONE'S inventory here in town....which is CRAZY. nor is it anywhere in the town an hour and a half away....so i ordered from eBay

my amp WILL live again!!!! mwahahahaha!!!

I only found one fuse, its on top of the circuit board. It is fine. i opened the power pack thing, and its impossible to get in with out ripping all the tape off and opening the metal cube. Could the speaker be blown out?

Did i mention that the power and everything turns on? the lights come on, and all that. i really think it could just be the speaker. and for tubes do they have lights in them?

Are you running any pedals and if so bypass, run guitar directly to the amp. Bypassing everything. If problem still persists try different cable. Then try a different guitar. Then take it to a amp tech if the problems still there.

It's probably not the speaker blown out if the sound faded out slowly. And even a blown speaker will make sounds, it will just sound really....bad. Best thing to do is to have a tech look at it.
#18
A speaker would make farty sounds, or make a popping sound when it failed and be visibly broken. If it was a fuse, it wouldn't turn on. If it was a powertube, you would have sound, but it wouldn't sound very good and it would loose about a third of it's volume. If your input jack broke, it would of been sudden. Sounds like something burnt up inside. Time to go to a tech. I would go ahead and take it to a tech just due to the fact you don't seem to know a whole lot about tube amps, which is not a good combo for trouble shooting/poking around inside.

FYI, there are not lights in a tube, it's simply the tube glowing when it warms up.

ok yeh, i knew about the "lights" in the tube, i think i will take it to a tech, do u know how much it will cost roughly?

No clue. Probably will be around $30-$50 to trouble shoot and diagnose the issue, and who knows how much to fix what ever is wrong with it. Hopefully it's not something like an output transformer, which could cost over $300 to fix.
