    i think they sent me the wrong tubes

    Hey guys im back again with my broken marshall. I have a tsl 100 head and i called because it had a bad hum and the guy at marshall said it's most likely the preamp tubes and he sent me new ones. now the tsl 100 has 4 12ax7 preamp tubes. The guy sent me 4 Sovtek EL84's. When i put the EL84's in, no sound came out at all and the tubes didn't even get hot, but when i put the old 12ax7's back in, the amp was working fine again, still humming bad obviously, but the 12ax7's were obviously doing something. So did the guy at marshall send me the wrong tubes? thanks in advance for the input guys.

        EL84s are not compatible with 12AX7s

          If it helps, the EL84's are worth more than the 12AX7's.

          Just trying to be positive.

          ((tube max dissipation wattage / amp plate voltage) x % of max dissipation wattage) x 1000 = bias current in mA

            The funny thing is EL84 are powertubes while 12ax7 are preamp tubes
