    I own a MarkBass Little Mark Rocker 500 as my only amp head. It has a mini tube powering a drive feature, but the tube appears to be soldered in place.

    I took it to an amp tech who said that everything seems clean, and in good working order. But I am used to being able to change tubes if they go out. Is there something I can do to prolong the life of the tube, or better maintain it?

    Thanks

    Wire in tubes have a very, very long life span. It'll out last you! :)

    Good to know, thank you! I just assumed it was like any other tube.

    Even normal preamp tubes have a very long life is they are not messed with and the amp is not intentionally destructive in design.

    Even if it goes out on you, its not hard for a good tech to solder a new one into it.
