Inside a $10K Amp | Secrets of the 1967 Marshall JTM50 BLACK FLAG Plexi | REPAIR & DEMO

In this video, we'll troubleshoot, repair, and demonstrate a RARE 1967 Marshall JTM-50 Plexi head. This amp was only made in this configuration for about ONE YEAR, so there are that many around. We may have to do some drilling / grinding on the chassis to accommodate an IEC replacement for the original Bulgin pignose power socket.
