    Can the Marshall JCM 800 2210 be used as a 50-watt head with only two power tubes?

    Hi people, hope y'all doing great. I was wondering if a Marshall JCM 800 2210 can be used with only two power tubes and if so which ones are to be removed? Has anyone done it? And is there a risk to blow the remaining two tubes from over-current?

    Dsl100hr Froggy Sound Bias At 0mv??

    So the other day I'm playing and all the sudden my sound starts cutting out like my instrument cable is bad. After going through the normal check list I'm certain it's the amp.
