check the tubes in the back and see if they're all lit up. replace the fuse, come back to us.

Original 5150 with stock tubes? lol, it's really time to change them man. Like was mentioned, it's probably a fuse inside the amp now. One of your tubes is probably arcing and blowing fuses.

so its a fuse caused by a tube? meaning i need a new fuse AND tubes? i figured it was the tubes, but id hate for there to also be a fuse in the amp. that means i have to bring it to a dang tech.

well, that's what's most likely, since they are so old. The fuse probably went if one is starting to short out. There are 4 fuses in the amp, they shouldn't charge you much if that's all it is. They are pretty easy to get to yourself if you wanted.

Most likely, the mains fuse died.


Fuses just don't die, unfortunately. Something kills them. Yeah, Gonna go with the dude that said you got a bad tube.

ok update + correction. now the amp turns on and the tube slight up, but no sound AND no standby light. the power light come son, but when i flip it off of standby that light doesnt come on. its like its stuck on standby lol

Did you check all the fuses? Got a multimeter? Pull the fuses and ohm them, I've seen those things blow on the inside near the end where you can't see.

i dont really have the tools, knowledge, or experience needed to open up an amp without being in serious danger lo. so i guess it needs to go into the shop?l

^Neither do i, but i'm about to open my ultra plus(Similar amp to yours) and replace the fuses..

I have the same problem as you.. lol. After i pop the fuse in i'll probably swap out the tubes from the crappy Svetlana's
#21
Take it to a shop. It's either an internal fuse or your power transformer or both.
Also could have been a tube arcing that caused more serious damage because you kept turning it on.
#22
Why do people keep saying "open it up and see if your tubes are lit."

You know, some preamp tubes don't really light up, even when they are functioning properly.
