Hi everyone, I recently had to change my power tubes on my haze 40 because there was a crakling sound coming out the amp. I have read that the tubes used by Marshall were Shuguang EL34b or ruby EL34b. I bought two pairs of each of them. With both of the pairs, the crakling sound was gone, but someth...

Ok so I am new here and I guess many guys asked that question already but I can't find an answer.

I tested m...

I hope that I will be able to find the exact same sound that I had before. I guess that it is a good idea to test how many mv I...

Anyway it seemed that it was one of the tubes, I changed it to spme JJ but the sound really changed for me. After reading a lot about this I found out that the stock tubes were actually EL34B Shugu...
