Horrible Static From Bogner Speaker Cab. Video Inclued

[randomdude]

Hey guys, out of nowhere my Bogner 2x12 speaker cab with Celestian V 30's is giving off horrible static. Nothing has changed in my setup so I have no clue what it is. I am sure its the speakers and nothing to do with the Bogner Atma head, but i am in no way a tech guy. I thought it was my guitar pots or switches or something but it gives off static with or without the guitar.

Please help guys. I have plugged the rig into other outlets in the house and have the same issue. I have plugged straight into the head without my pedalboard and still the same thing. All that makes me think its the speakers for sure.

Hopefully my description and video is enough to help me diagnose. I do have a warranty still with the bogner but really don't wanna ship that speaker cab from chicago to california lol.


Heres the video so you guys can hear this horrendous static that is making me crazy lol

ok, update for anyone who is interested. just got off the phone with a sweetwater tech. he had me switch the first and last pre amp tubes around to see if that was the cause of anything. something he said about inputs coming into one tube and out the other, didnt really understand it. he wanted to check that though. static was still happening though, so he then had me take out the 3 pre amp tubes one by one. after taking out each preamp tube the static/crackling was still there.

at that point he said its not the pre amp tubes and that he is pretty confident that swapping out the 2 power tubes will be the solution.

just ordered the exact JJ el84 pair from guitar center, i had a gift card, so when it comes in i hope thats the solution. he did say the atma is a type A amp so swapping the power tubes out means it does not have to be biased.

cheers everyone and i will give you another update in a week when the tubes come in. fingers crossed.
