![]() ![]() This creates a much larger and stronger solder joint and, along with the newly created space between the rectifier and the PC board, totally eliminates the heat problem. The longer leads are soldered to the traces on the back side of the board after insulation has been stripped from the traces to provide a larger solder pad. The cure is to replace the existing rectifier with a new rectifier with longer leads mounted with ample space between the PC board and the rectifier. This in turn causes a loss of high voltage DC current to the circuit that results in the amp cutting out or totally losing output. ![]() The rectifier produces a lot of heat and often eventually damages the solder joints on the back side of the board causing intermittent or open connections. The problem is a bridge rectifier installed on the PC board with no space between the rectifier and the board. If you own a Marshall JCM 2000 DSL 201 or 401 this is a mod you should consider. ![]()
