      Does a Cobra have a bias switch on it to change from 6l6 to el34? If not, your not going to able to do it without an amp tech.

          I think the most pertinent question before going any further. What cab do you have?

            I personally think different brands of tubes make no substancial difference. The amp either sounds good or it doesn't.

            Their impact on tone is often exagerated.

            +1 to "Cab" though.

              Open back cabs are gonna sound like dog shit with the Cobra considering they were designed and voiced around a front loaded, sealed back cab. You've got pretty much the exact opposite of what that amp was voiced for.

                Well, I guess we can rule out tubes as the culprit when you're running those cabs. Was it a 1960AV or 1960A you tried it with?

                  I've made the photos after having opened the backs, but i can close all holes! I always play closed back!!!.....and the cabs are front loaded...however i'm gonna try some pre amp tubes different from the jj....and sooner o later i'll change the powertubes with (i hope to find em) Ruby ones or svetlana....JJ are not good?

                  PS. I've tried the cobra with 1960AV (with vintage30 speakers)
