    I have an SWR IOD and it has the original Sovtek EL 84's (although they have just gone microphonic on me). Not keen on 'em anyway.

    So I need suggestions and descriptions of what Tubes you think I should buy. A description of why you feel that way would be good too.

    I play classic rock, some heavy some more bluesy but no Jazz or anything that requires a too clean or smooth sound.

    All opinions gleefully accepted :help:

    Its a matter of taste but I have been messing around with vintage vortexion studio equipment for a while using this tube type.
    And having rolled quite a few tubes, it seems to me that Brimar tubes are a little fuller maybe richer in the low mid bass but overall I think
    the mullard wins for most circuits using this tube.
    You know the old saying "Don't be a dullard use a Mullard"

    I use TAD (tune amp doctor) in mine which are very robust. Not sure how much of a difference they made over the ones that were in there previously. I think a larger effect is the bias - play around with it if you a comfortable - I wouldn't recommend that in a normal tube amp power section but it should be fine in this design. There is a trimmer pot inside the unit and it has a reasonable effect on how clean or nasty things get.
