Repairing a VINTAGE TUBE BEAST! - 1971 Marshall Super Lead 100W Model 1959

In this video, we will assess the condition of a CLASSIC 1970s Marshall JMP Super Lead 100W head and begin the troubleshooting and repair process. The model is a 1959. This is not a Plexi, as the faceplate is brushed metal, not plexiglas. This is the 100W version of the 50W 1987.
