Johnson Amplification Marquis JM60
« on: September 26, 2022, 12:58:56 pm »
I've posted this in another forum, too, but I'm looking for schematics for this unit.  It seems to be a pretty rare one, but hoping someone might have some more info on this.  Thankfully, all I'm going to be doing to it is swapping out a bad input jack, but I am curious of the internals and would love to get my hands on a schematic or service manual if anyone has one??  Any help would be appreciated.
