Problem with Engl Screamer

StrangeSound

GlossesForNothin'
Hey there!

I got this awful noise (like knocking on a trash can) when I play certain notes on the guitar or knock on the amp.

It sounds as if I knock very hard but it only needs few power to cause the effect. I'm stark-mad.

I changed the preamp tubes already among each other but no change.

Could install the old power tubes but they aren't supposed to run that hot.

Any ideas?

Poltergeist!
Damn that is one weird noise, and the hissfloor goes up and dwon as well!
LOL..Poltergeist indeed! :laugh2:

The reason why the hissfloor changes is I held the mic with my hand.

Yeah..I think the amp is obsessed..needs an exorcism.

I will put the old tubes in it, although they aren't made for a bias that hot..but for some minutes it'll work..I guess.
 
Re: Problem with Engl Screamer

The anodes glow white..had the amp on for some seconds but didn't play something. Although it was just 10 seconds...I couldn't hear the Poltergeist.

Perhaps I should buy a pair of JJs (should be about 41ma) and throw it in. If that doesn't work I'll take it to a tech and have some spare tubes.

I survived :D

If I shake one of the new =C= powertubes nearby my ear..it rattles. Well the other too. I do it gently..the stock Engl ones are quiet.

Ah, 4 already! My brain messed up :D

But less than half a year, so I bet my money on JJ now. :)

But well, can't use the amp with broken tubes. Going back to my roots...Marshall MG 30 :D

I just found the bias trimpot..Hurray!!!! :dance:

I'll order a pair of JJ 6L6 tubes, a bias probe and a multimeter and I can do that thang on my own :->

Perhaps the bias was too hot and the tubes died because of this..have to check out the plate supply.
