    Hey There,

    I know there are tons of threads about biasing but I have some specific questions so I thought I'd start a new thread.

    I want to bias my 1973 Marshall Superlead.

    I'm thinking of building this probe:

    TubeDepot Bias Scout Kit

    I've located the bias trim pot: (the black round 25k pot by the 2 yellow caps)


    So... Is it going to be a problem to only have a 1 socket probe? Will I need to test 1 outside socket and 1 inside socket and find a happy medium?

    Is this the correct information on what to set the bias at (EL34)
