    Apparently one of my preamp tubes is bad, and of course they are the only thing NOT covered under warranty. So...my question is:

    Replace just the bad tube (came with JJ Electronics 12AX7)?
    Replace all 3 with a different brand since the JJ crapped out after 8 months (Mullard)?

    Or...

    Are there other options of tube type to get better sound?

    I know extremely little about tubes... I've read about matched sets, NOS, etc, etc...but don't know if it would make much of a difference being it's only tube preamp.

    Any advice would be appreciated
