AAAAAAAAAAAH my triple x blew up or sumthin!!!!!

[Bigfknbang]

HELP ME!!!!! ok heres what happened. i have a 60 watt peavey xxx 1-12 combo. it has a switch for either 6l6's or el34's. i had 6l6's in there and got some el34's to try cause i wanted to see whitch i liked better. i put the el34's in and there is this little bias knob thing i dont know what that does. i dont know if i might have bumped it if that would do anything?? but anyway i put the switch to el34's and put em in and played played on it for like 30 mins or so and it seamed fine and i liked how it was sounding. then just now i turn it on and start playing and it makes this big POP sound and all sound goes out. if i turn it up all the way i can hear it. what did i do??? i put the 6l6's back in and it still doin the same thing. did i blow a transformer or sumthin? help me out please!! thank you for any help! joe s.

Sounds like a bad tube. or a cracked tube socket. Put the 6l6's back in and see if it works.

i did put them back in. its still doing the same thing. the tubes heat up but there is no volum until i crank it full blast. and then its this real raspy weird distortion on the distortion channels and no sound on the clean channel. this sux!!!

Check all your cords. Try pulling the tubes and reinstalling them. Sounds like maybe a bad solder joint on a power tube socket. If it was a transformer you would usually smell or see smoke. Transformers smell aweful when they blow. When you pulled the original tubes you probably dislodged a bad solder joint that was always there.

thank you, ill check it. one of the el34's is all white and has white powder in it also. i got this amp off of ebay about 6 months ago and UPS dropped the frgn thing. broke the footswitch. the amp was workin fine besides the footswitch so i didnt flip out totaly. but maybe when they dropped it messed it up? thanx again ill check the socket.

A bad solder joint would cause you to blow up a tube because of a voltage arc. I would remove all the tubes and take the amp apart and chek for a bad solder joint on the socke with the cooked tube. IF YOU DON'T KNOW WHAT YOU ARE DOING... STOP!!!! THERE IS ALOT OF DANGEROUS VOLTAGE INSIDE THAT AMP EVEN WITH IT UNPLUGGED WITH THE TUBES OUT. CAPACITORS ARE LIKE LITTLE BATTERIES. THEY HOLD A CHARGE AND ARE JUST WAITING TO ZAP YOU GOOD.

take it to a tech. it's gonna need to be opened up to fix it, and if you don't know what the bias knob is for, you have no business poking around inside an amp; that sort of thing can get you killed if you don't know what you're doing.

[Bigfknbang]

ok im not gonna mess with it thanx again!

ok im not gonna mess with it thanx again!

Did it go out with a Bigfknbang, or a whimper?

[TheAmazingBlob]

Could be a fuse or a power tube socket, as said... I'd take it to a tech, this isn't really a DIY sort of thing.

[Bigfknbang]

thanx guys. im gonna take it up to the shop when i make my next payment on my dk2m. hope it doesnt cost me an arm n a leg to fix it.

Although it appears to be physically related to a power tube change....

Being you can hear it somewhat on one channel and not the other would make me initially look to a preamp tube. Power tubes issue would likely do it all the time.

I spose a failing power tube could have damaged supporting circuitry like a grid circuit or something. But that would probably show all the time too.

Check out the preamp tubes. Move them around between sockets and see if the issue changes.
